IIT Bombay GC MS

Hi I would like to have knowledge about Gas Chromatography Mass Spectrometer as well as details about Gas Chromatograph with high resolution Mass Spectrometer and the analysis which is possible using the instrument?

[Rajkumar Agarwal]

GC-MS is a capable explanatory procedure for partition, distinguishing proof and measurement of unpredictable natural and inorganic mixes in a dissolvable blend. It is an exquisite interfaced instrument, in which the Gas chromatography (GC) first isolates the segments of a blend and after that the coupled Mass spectrometer (MS) portrays each of the isolated segments independently.

The parts are isolated in light of their relative fondness or maintenance time of the individual mixes. Amid the procedure, the very much isolated mixes from the GC are exchanged to the interfaced MS instrument and get fragmentized into particles by ionization prepare.

The resulted divided particles gets isolated in light of their m/z (Mass/Charge) proportion and it creates a mass range (Distribution of mass to charge proportion Vs Signal power) for every segment. This instrument is broadly utilized as a part of the Medical, Pharmacological and Law authorization fields.
