Stability sample charges as per guidelines
1. Charging Samples to a Stability Study (Initiation):In the pharmaceutical industry, “charging” samples to a stability study refers to the process of formally placing representative samples of a drug substance or drug product into controlled storage conditions (e.g., specific temperatures and humidity levels) according to a predefined stability protocol. This is the starting point of a stability…

Heavy metal -B
Method B in heavy metal testing is used for substances that do not yield clear, colorless solutions when tested under Method A. It involves reacting the sample with hydrogen sulfide or sodium sulfide to form colored metal sulfides, which are then compared to a standard lead solution to determine if the sample meets the limit of 20 parts per million for heavy metals. Here’s a more detailed…
