• High-Performance Liquid Chromatography-Tandem Mass Spectrometry
High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) is a sophisticated analytical technique that integrates high-performance liquid chromatography (HPLC) with mass spectrometry (MS) to separate, identify, and quantify target molecules in complex samples. HPLC is utilized for the efficient separation of diverse components within a sample, while MS provides highly sensitive and selective detection through ionization and analysis of the mass-to-charge ratio (m/z) of molecules. Ta......
