GMP Inspection Checklist & Most frequently asked questions about HPLC
HPLC is an abbreviation for High-Performance Liquid Chromatography. “Chromatography” is a technique for separation, “chromatogram” is the result of chromatography, and “chromatograph” is the instrument used to conduct chromatography. HPLC dedicated to molecular separation called columns and high-performance pumps for delivering solvent at a stable flow rate are some of the key components of chromatographs. Only compounds dissolved in solvents can be analyzed with HPLC. HPLC separates compounds dissolved in a liquid sample and allows qualitative and quantitative analysis of what components and how much of each component is contained in the sample.
