Reference And Working Standards For Good Pharmaceutical Products

Reference standards are one of the key factors for consistently good quality of Pharmaceutical Products. They are used as Primary or Secondary standards for the quality control of Active Pharmaceutical Ingredients (API) and Finished Products.

Quality Control in our Laboratory is responsible for testing 227 Active Pharmaceutical Ingredients (API) and Finished Products produced by Manufacturers. For the analyses of this number of different substances and products, we are handling with Sophisticated Instruments like High-Performance Liquid Chromatography with Auto-sampling System & Gas Chromatography with Head Space with skilled and trained personnel.

Within Tamilnadu Test House, chemical reference standards are centrally managed and coordinated by a controlling manager with decentralized analytical testing by laboratory experts. Linked to their routine use, four types of RS are defined: Primary standards (PS) and Working Standards (WS) for content and identity determinations, Reference Materials (RM) for identification purposes and system suitability testing, and Official Standards (OS) for both, depending on the user-defined by the compendia.

The declared content of PS is calculated on an as-is basis taking all-determining components into account. The same procedure is applied for WS (if purity >98%) in order to minimise the propagation of errors. The calculated result is verified vs. a content determination using a PS or compendia standard, or an absolute content method.
