How to Read LC-MS Chromatograms

Liquid chromatography - mass spectrometry (LC-MS) combines two approaches to separate and identify molecules or compounds present in a sample. High performance liquid chromatography (HPLC) separates components of a mixture, whereas mass spectrometry (MS) offers the detection tools to identify them. LC-MS, as a method for understanding biological molecules, has applications in both research and clinical diagnosis.
