WebLiquid chromatography-mass spectrometry (LC-MS) is the combination of two selective techniques that allows the analyte(s) of interest in highly complex mixtures to be isolated and measured. LC differentiates compounds by their physico-chemical properties and MS differentiates compounds by mass (specifically their mass-to-charge ratio). WebThe sensitivity of the system is extremely important in most MS analytical tasks. Heated electrospray helps to increase ion yield. Compared to standard electrospray, the VIP-HESI offers a solid gain in sensitivity for many compounds of interest in the fields of metabolomics and pharmaceutical analysis, environmental analysis, food testing and forensic drug …
