Instrument control and treatment of results

With commercially available programs, the computer can carry out the following operations. 

The acquisition program allows the operator to choose the scan mode or the SIM mode, the range of masses that are scanned, either low or high resolution, and so on. The acquisition processor is set according to the data given by the operator concerning the analysis to be carried out. Most recent instruments are entirely electronically controlled from parameters 

An interactive program that lets the operator intervene and modify the parameters at any time allows the investigation of the chromatographic results. Usually, it allows the following operations  

The operator can use magnifying effects on this chromatographic trace to select part of the chromatographic trace and enlarge it over the whole screen, or amplify the 

Deconvolution of a chromatographic peak containing two compounds. Spectrum 212, where the background noise was subtracted, is different from 215. The two spectra are obtained by the appropriate subtraction.
