Assay Method Validation Introduction: Assay method validation is one of the most important activities in pharmaceutical analytical development. Before an analytical method is used routinely for testing a drug substance or drug product, it should be demonstrated that the method is suitable for its intended purpose. In simple words, assay method validation proves that an … Read more

GMP Good Manufacturing Practices: GMP is one of the most important concepts in the pharmaceutical industry. It ensures that medicines are consistently manufactured and controlled according to predefined quality standards. GMP is not limited to testing the finished product; it covers the entire manufacturing process, including raw materials, equipment, personnel, documentation, production, quality control, packaging, … Read more

Loss on Drying (LOD) Calculation Formula: Loss on Drying (LOD) is a common test used in pharmaceutical quality control to determine the amount of volatile matter lost from a sample during drying. It is widely used for APIs, excipients, intermediates, and pharmaceutical products to monitor moisture and other volatile substances present in the material. Although … Read more
