A TIC (Total Ion Chromatogram) is a chromatogram created by summing up intensities of all mass spectral peaks belonging to the same scan. The TIC is compared to a GC chromatogram. Note that the TIC includes background noise as well as sample components.
What does a total ion chromatogram tell you?
The total ion current (TIC) chromatogram represents the summed intensity across the entire range of masses being detected at every point in the analysis. ... In complex samples, the TIC chromatogram often provides limited information as multiple analytes elute simultaneously, obscuring individual species.
What is the difference between a total ion chromatogram and a mass chromatograph?
The difference is that each point in the chromatogram is actually a mass spectrum. Thus a mass spectrum can be retrieved for any peak in the chromatogram. Conversely, a selected ion chromatogram can be retrieved for any mass.
