HPLC operates on the basis of differential partitioning of analytes between a stationary phase (typically a modified silica column) and a mobile phase (solvent system). Components are eluted at characteristic retention times...
High-performance liquid chromatography (HPLC) is the primary tool for evaluating the quantitative and qualitative composition of a substance. It separates all components of a sample and shows exactly what it contains: the active...
Many active substances — from hormones to biological products — are highly temperature-sensitive. Even a brief deviation from the required range can alter a molecule’s structure, reduce its activity, or make the...
Substance purity is a critical factor for the safety and stability of any pharmaceutical product. The reliability of the final medicine — and the absence of risks for distributors — depends on...
