LC–MS (Liquid Chromatography–Mass Spectrometry) Description: LC–MS (Liquid Chromatography–Mass Spectrometry) is a powerful analytical technique that combines liquid chromatography (LC) with mass spectrometry (MS) to identify, separate, and quantify chemical compounds in a sample. In the first step, Liquid Chromatography separates the mixture into individual components based on their chemical properties such as polarity and solubility. Then, these separated compounds enter the Mass Spectrometer,
