The Science Behind LC-MS/MS: A Detailed Explanation
Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (LC-MS/MS) represents a powerful analytical process widely utilized in various disciplines, including metabolomics and food analysis. The process includes two sequential stages: Liquid Chromatography (LC) and Tandem Mass Spectrometry (MS/MS). Initially, LC serves to resolve intricate substances based on their chemical properties. This resolution happens as the sample passes through a bed containing a defined stationary phase. A flowing phase, meticulously selected, transports the resolved compounds to the mass spectrometer. The MS/MS system then fragments the charged molecules formed by the LC, creating characteristic signatures. Specifically, the first mass analyzer picks a parent ion, which is then broken by a collision impact. The resulting daughter ions are then measured by a second mass analyzer. This sequential mass evaluation provides exceptional precision and specificity, enabling the quantification and quantification of low levels of analytes within a complex environment.
