The Science Behind LC-MS/MS: A Detailed Explanation
Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (LC-MS/MS) is a powerful analytical method frequently utilized in various areas, including metabolomics and food analysis. The process comprises two distinct stages: Liquid Chromatography (LC) and Tandem Mass Spectrometry (MS/MS). Initially, LC acts to resolve complex samples based on their hydrophobic traits. This resolution occurs as the specimen moves through a bed containing a defined immobile phase. A flowing phase, precisely chosen, moves the resolved compounds to the mass spectrometer. The MS/MS instrument then cleaves the particles produced by the LC, creating characteristic fragments. Specifically, the first mass analyzer chooses a parent ion, which is then broken by a collision impact. The resulting product ions are then detected by a second mass analyzer. This multi-stage mass analysis delivers exceptional sensitivity and selectivity, allowing the detection and determination of trace amounts of targets within a complex sample.
