WebWhat's the second best way to learn to read GCMS output? Because I know the best way is just to do it for 10 years. I'm working in a toxicology lab and it seems like there are so many nuances and little tricks that I would never think to do. Also, learning where the peaks occur from which drugs and the ions those drugs break down to. WebWhen the vaporized organic sample passes into the ionization chamber of a mass spectrometer, it is bombarded by a stream of electrons. These electrons have a high enough energy to knock an electron off an organic molecule to form a positive ion.
WebDec 27, 2013 · The chromatogram is a two-dimensional plot with the ordinate axis giving concentration in terms of the detector response, and the abscissa represents the time. The detector gives a response as a peak whose height should be ideally dependent on the concentration of the particular component. Retention Time (tr) Web1.
