WebMass Spectrometry is quintessential technology, and as such there are many platforms available -- from triple quadrupole to hybrid quadrupole/time-of-flight (QTOF) devices and others depending on the intended application (s). When shopping, key metrics to consider are: resolution, sensitivity, speed, throughput, and versatility. WebIn conventional LC-MS/MS experiments a sample is initially analyzed by mass spec trom etry to identify the molecular ions of the peaks of interest. The sample is then analyzed further by performing product ion MS/MS scans on the selected peaks. This is a time-consuming process because the sample needs to be run at least twice and the MS/MS
