The Science Behind LC-MS/MS: A Detailed Explanation
Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (LC-MS/MS) represents a versatile analytical technique widely utilized in various disciplines, including metabolomics and environmental assessment. The mechanism includes two sequential stages: Liquid Chromatography (LC) and Tandem Mass Spectrometry (MS/MS). Initially, LC serves to isolate mixed substances based on their physical traits. This partitioning happens as the material passes through a bed containing a particular stationary phase. A eluent phase, precisely selected, carries the isolated analytes to the mass spectrometer. The MS/MS apparatus then cleaves the ions generated by the LC, creating characteristic fragments. Specifically, the first mass analyzer picks a parent ion, which is then fragmented by a collision impact. The resulting daughter ions are then analyzed by a second mass analyzer. This multi-stage mass examination provides exceptional detectability and selectivity, permitting the quantification and measurement of minor levels of compounds within a complex sample.
