Automated Flash Point Analyzers in Petroleum Quality Control

The flash point of a petroleum product—the lowest temperature at which vapors above the liquid ignite in the presence of an ignition source—is a critical safety and quality parameter. Traditionally, determining flash point relied on manual Pensky-Martens or Cleveland open cup methods, which are labor-intensive, subject to operator variability, and require significant warm-up times. Over the past decade, however, automated flash point analyzers have revolutionized routine quality control in refineries, laboratories, and distribution facilities.

Principle of Operation

Automated flash point analyzers typically use a closed-cup configuration, conforming to ASTM D93 standards. A small sample is placed in a sealed cup equipped with a temperature sensor and drugged stirrer. Heating is precisely controlled via a programmable microprocessor, raising the sample temperature at a uniform rate (often 1–6 °C/min). At defined intervals (for example every 1 °C rise), a miniature electric ignition source is introduced into the vapor space. The instrument’s optical sensor then detects the appearance of a flame or “flash”—automatically recording the corresponding temperature. Because the cup is closed, volatile compounds remain contained, improving repeatability and safety.

Key Features and Benefits

Automation and Reproducibility

Compared to manual methods, the automated process minimizes human error. Programmable routines ensure consistent heating rates, stir speeds, and ignition intervals, leading to repeatability within ±0.5 °C. The analyzer’s microprocessor logs all test parameters and results, creating an audit trail in digital or printed form.

Safety Enhancements

Closed-cup systems contain hazardous vapors, reducing operator exposure and risk of accidental fires. Many units feature built-in safety interlocks, flammable vapor detectors, and emergency ram dump functions that rapidly seal the sample cup in case of volatility anomalies.

Faster Throughput

Modern analyzers can complete a flash point determination in as little as 5–10 minutes per sample—up to 50 % faster than manual methods. Instruments often offer “quick test” modes, which use an accelerated heat rate and wider ignition intervals for preliminary screening, followed by a confirmatory detailed run if needed.

Compliance and Reporting

Instruments are designed to meet ASTM D93, ISO 2719, and IP 34 standards. Built-in software can generate customizable reports, flag out-of-spec results, and interface with LIMS (Laboratory Information Management Systems) via Ethernet or USB. This seamless connectivity streamlines data management within modern petroleum laboratories.

Applications

Fuel production and storage: Ensuring gasoline, kerosene, and diesel meet flash point specifications for safe handling and transport.

Marine and aviation fuels: Verifying stringent flash point requirements (e.g., jet fuel minimum flash point 38 °C) to comply with international regulations.

Lubricants and specialty oils: Evaluating base stocks and additives to guarantee consistent performance under varying thermal conditions.

Maintenance and Calibration

Automated analyzers require periodic maintenance to ensure sensor accuracy and mechanical reliability. Routine checks include verification of the temperature probe (using certified calibration baths), inspection of the ignition electrodes, and replacement of seals and O-rings. Many manufacturers provide auto-calibration kits or service contracts to maintain compliance.

Future Developments

Emerging technologies integrate rapid infrared heating and non-contact optical detection, further reducing test times and maintenance burdens. Coupled with AI-driven diagnostics, next-generation flash point analyzers will predict maintenance needs, self-optimize test parameters based on sample type, and offer cloud-based data analytics for global quality assurance networks.

Automated flash point analyzers exemplify how advanced instrumentation enhances safety, accuracy, and efficiency in petroleum testing—critical for both regulatory compliance and operational excellence.

The Revolution of Ultra-Thin LED Display: Technology and Applications

Email: sale05@xygledscreen.com

WhatsApp & Wechat: +86 18038197291

www.xygledscreen.com

Ultra-thin light-emitting diode (LED) displays are set to change the way we consume digital content and interact with our surroundings. With incredibly thin screen sizes and displays that could be applied to just about anything, these cutting-edge screens present several exciting opportunities across industries, including medical devices, advertising, transportation, and gaming. In this article, we'll take an in-depth look at the technology behind ultra-thin LED displays and how they are used today.

What is a paper-thin/ultra-thin LED screen?

A paper-thin/ultra-thin LED screen is a type of display technology that can be bent, rolled, or shaped into any shape. Paper-thin led screens are extremely lightweight, with a thickness that can range from 0.1 mm to 1 mm. It may sound hard to believe, but these screens are thinner than the average piece of hard paper! In addition, ultra-thin led displays also use less power than LCDs and are highly durable.

With single-color LEDs and wireless connectivity via Bluetooth, paper-thin led screens are quickly becoming more common in multiple industries.

Whether working with a paper-thin screen at home or at your workplace, you'll probably find one product that perfectly suits your needs. For example, if you have a small retail business and would like to display prices to customers, an ultra-thin led screen can work perfectly in that setting. More on this in a short while.

The technology behind ultra-thin LED display

Ultra-thin LED displays consist of a substrate, an anode, a cathode, a conductive layer, and a light-emitting material. The substrate is typically glass or plastic. The cathode consists of a silver-coated electrode, while the anode consists of a transparent conductor such as indium tin oxide (ITO). Two layers of conductive ITO are on top of each other to achieve better electrical properties. A high voltage is applied between the two electrodes, which makes electrons flow through the light-emitting material, causing it to emit light.

In order to reduce thickness, manufacturers need to reduce the space needed for the conductors by working with new materials that are more flexible than those currently in use.

These new materials include carbon nanotubes, graphene, and metal nanowires.

This new material can be printed onto flexible substrates, making these screens rollable and foldable like paper.

In addition, because this new material is cheaper than current ones, it would also make manufacturing processes less expensive. Manufacturers could then create smaller displays at lower costs due to their improved production methods.

LED screens are thinner, brighter, and more energy efficient than LCDs. The average lifespan of LED display technology will continue to grow longer since LEDs do not burn out easily.

The applications and advantages of choosing an ultra-thin LED screen

Owing to their numerous advantages over traditional display screens, many companies are now opting for these ultra-thin displays.

Advantages of Ultra-thin LED screens

Here are the benefits of ultra-thin LED screens: 

* Lower energy consumption - Paper-thin LED displays do not need a backlit screen. Instead, a layer of light-emitting diode lights up when a current is passed through them. This reduces power consumption by as much as 85% compared to LCDs (Liquid Crystal Displays). They are thus suitable for battery-powered devices like smartphones.

* Highly versatile - Due to their small footprint and lower power consumption, they are highly suited for many devices, including mobile phones, laptops, and tablets. Even portable gaming consoles benefit from these screens.

* Versatility leads to reduced costs - As paper-thin led screens don't require any heating or cooling mechanism, they can be fitted into smaller spaces, leading to significant cost savings. Their compact size makes it easier to make space for extra components inside the device while reducing production costs because they can be mounted on flat surfaces, unlike bulky LCD panels.

* Superb image quality - Paper-thin LEDs like OLED (Organic Light Emitting Diode) have the advantage of producing deeper blacks and richer colors than regular LED screens because three individual light sources make each pixel. The result is a very high resolution, often dwarfing FullHD by up to 16 times.

* Fast response time - They respond to touch within 50 milliseconds, which is fast enough to do away with the trail effect. This makes these displays more suitable for use in HD applications like gaming or at home.

Applications of Ultra-thin LED screens

These displays also find application in communication devices such as televisions. Major television manufacturers such as Samsung, Sony, and Panasonic now offer ultra-thin TVs that produce sharper images with less motion blur than other televisions available in the market. Moreover, due to its low power requirements, this technology will also be suitable for future quantum computers where even the smallest form of heat could interfere with calculations.

Other applications include:

1. Commercial and professional displays where they are used in control rooms, broadcast rooms, and other areas where larger displays are needed;

2. Large format signage, advertising, and video walls;

3. Medical equipment such as patient monitors and medical imaging systems;

4. Sports scoreboards and digital clocks that take up less space than conventional ones;

5. DOOH makes advertisements interactive and engaging; DOOH is a preferred method among marketers to engage customers.

6. Outdoor lighting displays, for instance, are possible thanks to the low-heat generation and longevity of LED screens.

7. They can be found in places such as casinos, malls, and amusement parks.

Recommended Unilumin ultra-thin LED product (28mm ultra-thin design) with case studies

Unilumin's 28mm ultra-thin design is the world's smallest, lightest, and most energy-efficient display. With superior brightness to the competition and a full suite of features that can be customized for any application, this new LED technology is redefining the landscape for modern displays.

According to a paper published by John Rogers, the Flory-Founder Chair Professor of Materials Science and Engineering at the University of Illinois, organic LEDs, such as those used in Unilumin's 28mm ultra-thin design, are superior as they combine the aspects of inorganic LEDs and the ordinary OLEDs. This results in brighter, more robust, and more durable displays.

The process of cloning these two technologies into a single one involves interconnecting ultra-thin LED layers by film processing. The result is a high-resolution system, otherwise impossible to make by ordinary inorganic LED manufacturing processes.

Zircon chooses Vetaphone for its narrow web presses

One of India’s leading label and packaging converters, Zircon Technologies, is installing an Omet Varyflex 670 press fitted with a Vetaphone corona treater at its production facility in Uttarkhand capital Dehradun, some 250km north of Delhi.  The company already has Vetaphone corona technology on its existing two Omet and seven Mark Andy presses.

Established in 2007 by owner and managing director Sanjeev Sondhi, the company, which employs 450 people across five sites, produces more than 40 million square metres of printed material each year.  Markets supplied include food & beverage, healthcare, industrial, and pharmaceutical sectors, with a range of products from labels and flexible packaging to anti-counterfeiting and brand authentication items, as well as shrink sleeves, pouches, and blister packs.

With a high-quality portfolio of international brand owners to service, Zircon prides itself on its end-to-end support from R&D through to delivery of the finished product.  According to Sondhi, “We have stringent quality and delivery processes in place to ensure our products can be put straight onto our customers’ production lines at the time requested – what’s more, we can automate production for a seamless solution.”

Working typically with PE and aluminium foil, corona treatment was always going to be required to ensure good ink adhesion. Two of the Mark Andy presses are fitted with Vetaphone corona technology as well as the Italian-manufactured Omet VaryFlex 430 flexo press that is configured to some proprietary web passes and attachments to meet Zircon’s requirements.  Fitted with automatic registration control and the facility to print back and front in a single pass, the Omet is capable of printing substrates from 12-micron film to 600-micron board.

As Mark Andy and Omet are both leading OEM customers of Vetaphone, the Danish company’s corona technology was an easy choice.  The Mark Andy presses are fitted with VE1A-A corona treaters with four ceramic electrodes in their removable cartridges.  Each has an iCorona-1UL generator, one with 1.5kW power, the other with 2kW.  The Omet has two VE1A-A treaters with four ceramic electrodes and 2kW iCorona generators.

“We were aware of other options for surface treatment but decided to go with Vetaphone.  They invented and have pioneered corona treatment and came highly-recommended as a trusted and reliable brand,” said Sondhi, who is looking to grow his business in the aluminium packaging, screen printing and stand-up pouch markets, where the non-absorbent substrates will all need surface treatment.

With Diageo, Yamaha, and Pernod Ricard among its 300 customers, Sondhi knows that only state-of-the-art technology will allow him to deliver the quality demanded.  “I am very satisfied with the Omet/Vetaphone combination – it allows our team of skilled professionals to offer customers what they want, when they want it, and at a quality and price that meet their expectations.”  With 7 in 10 consumers admitting that packaging influences their purchasing decision there is a premium on getting it right first time, every time.

Biosensors, Vol. 14, Pages 110: Studies on the Aptasensor Miniaturization for Electrochemical Detection of Lead Ions

Lead poses severe effects on living organisms, and since Pb2+ ions tend to accumulate in different organs, it is crucial to monitor Pb2+ concentration in samples such as water and soil. One of the approaches is the utilization of biosensors combined with #aptamer-based layers for the electrochemical detection of lead ions. Herein, we present the studies of applying miniaturized screen-printed transducers as solid surfaces to fabricate #aptamer layers. As the research is the direct continuation of our previous studies regarding the use of gold disk electrodes, the working parameters of elaborated aptasensors were defined, including the range of linear response (10–100 nM), selectivity as well as stability, regeneration, and feasibility of application for the analysis of real samples. This was achieved using voltammetric techniques including cyclic and square-wave voltammetry in the presence of methylene blue redox indicator. https://www.mdpi.com/2079-6374/14/2/110?utm_source=dlvr.it&utm_medium=tumblr

Biodegradable sensor monitors levels of pesticides via direct contact with surface of fruit and vegetables

- By Julia Moióli , Agência FAPESP -

Researchers at the University of São Paulo (USP) and the Federal University of Viçosa (UFV) in Brazil have developed a sustainable sensor that can be placed directly on the surface of a vegetable or fruit to detect the presence of pesticides.

Known for this reason as “plant-wearable”, it is made of cellulose acetate, a material derived from wood pulp.

The device has the potential to help assure food safety in a world that increasingly suffers from a shortage of food and the environmental and health problems caused by excessive use of agrochemicals. 

An article describing the results of the study is published in the journal Biomaterials Advances.

Pesticides are widely used to raise crop yields and are typically applied by spraying, but only 50% reach their target. The rest ends up in soil, groundwater, surface water, raw drinking water, wastewater and food products. Monitoring of pesticide levels in water, soil and food is therefore essential to prevent contact between these toxic substances and the public via the skin, lungs or digestive system.

The analytical tools most often used for this purpose are chromatographic techniques, which are effective but have drawbacks such as the need for pretreatment of samples, expensive equipment and qualified laboratory specialists, as well as the long time taken to complete the analysis and lack of portability. The unsafe residues produced by organic solvents are also a significant problem under present-day conditions.

“As an alternative, electrochemical sensors can combine affordability, rapid detection, miniaturization, large-scale production, convenience, ease of use, high selectivity and in situ pesticide detection. Our invention has all these features. The analysis is performed directly on the surface of fruit, vegetables or leaves. Hence the term plant-wearable,” said Paulo Augusto Raymundo-Pereira, last author of the article and a researcher at the São Carlos Physics Institute (IFSC-USP).

“However, instead of the usual materials, which are environmentally unsustainable and take a long time to degrade, such as ceramics or plastic polymers derived from petroleum, we used cellulose acetate, a material derived from plants that has little impact on the environment and disintegrates completely in 340 days or less depending on local conditions. Of course, it has to have appropriate characteristics for any sensor, including low cost, portability and flexibility.”

The biodegradable cellulose acetate substrate was produced by a casting method in which the material was placed in a space with the required shape, and the full electrochemical system with three electrodes was deposited by screen printing.

The researchers carried out laboratory tests in which a solution containing carbendazim, a fungicide, and paraquat, a herbicide, was sprayed on lettuce and tomatoes in a simulation of real-world use. Paraquat was banned by the European Union in 2003 owing to its harmful effects on humans but is still used in Brazil. The sensor was then directly attached to the lettuce and tomatoes, and measurements showed a level of detection compatible with those obtained with polyethylene terephthalate, the sensor material most frequently used for this purpose.

Excessive pesticide levels

The study, which was funded by FAPESP (projects 20/09587-8, 23/07686-7, 16/01919-6, 22/02164-0 and 23/09685-8) also investigated whether washing and immersing vegetables in a liter of water for two hours was effective to remove pesticide residues. The results showed removal of 40% of the carbendazim and 60% of the paraquat from lettuce, and 64% of both from tomatoes.

“Washing and immersion were clearly insufficient to remove residues of the pesticides. At least 10% remained in the leaves or peel,” Raymundo-Pereira said.

The technology can be useful for sanitary surveillance agencies worldwide, he added, as well as sellers of organic produce to certify absence of pesticides. Farmers generally can use it to monitor levels of pesticides in the field and be sure of applying only the requisite dose to each crop or part of a plantation. Pesticide use could decrease as a result, while yields will still rise, leading to lower consumer prices.

Besides the IFSC-USP team, the following researchers also took part in the study: Samiris C. Teixeira, Nilda de F. F. Soares and Taíla V. de Oliveira at UFV; and Nathalia O. Gomes, Marcelo L. Calegaro and Sergio A. S. Machado at the São Carlos Chemistry Institute (IQSC-USP).
