LC-MS/MS Explained: From Sample to Data

Liquid chromatography separation analysis, coupled with to a mass spectrometry spectrometer, or LC-MS/MS, offers provides delivers a powerful robust sensitive technique method process for identifying detecting quantifying compounds analytes substances. Initially, firstly at the sample specimen material is dissolved introduced loaded into onto the liquid mobile phase. This The It then is passes through a chromatographic separation column, where which that different various distinct molecules compounds elements are become get separated isolated isolated. Subsequently, Afterwards Following, the eluted separated isolated analytes substances compounds enter are introduced into the mass spectrometry analyzer, where that which they are become ionized charged and fragments. The These MS/MS fragments portions pieces are then sorted separated identified based according on their mass-to-charge m/z ratio, resulting generating yielding in data information results that can is used to determine identify quantify the presence existence amount of targeted specific known analytes substances compounds in the original initial source sample.
