From pH to UPLC-MS-MS

Originally developed as a reference testing laboratory, KABS steadily improved its facilities, instrumentation and quality systems in response to market demands for advanced analytical R&D approaches that are pre-requisites for the successful development of complex drug products.

 

Development and validation of stability indicating analytical methods

Raw Materials
APIs, Excipients and Additives: Assay, Impurities/Degradation products and Organic Volatile Impurities.
Manufacturing Processes
Cleaning validation: Traces of active ingredients, residual detergents.
In-process testing: dissolution, content uniformity, hardness, thickness, viscosity, etc.
Finished Products
Tablets, capsules, syrups, gels, creams, aerosols, sterile injectables: Assay, impurities, OVI, dissolution, long-term and accelerated stability studies.
Chromatographic Instruments Selection
