I have picked up a textbook on mass spectrometry, and I am finding it did not clearly distinguish between total ion chromatogram (TIC) and total ion current chromatogram (TICC) in the section (1.3 Ion Chromatograms) I just read. I suspect there was some sort of typo, but I don't have the experience to tell yet.
Here is an abridged excerpt from the textbook that has confused me:
The total ion current (TIC) can either be measured by a hardware TIC monitor before mass analysis (nA to uA range), or its equivalent can be reconstructed or extracted after mass analysis. [...] Thus, the TIC represents a measure of the overall intensity of ion production of ion production or of mass spectral output as a function of time, respectively. The TIC obtained by means of data reduction, [...], is termed total ion chromatogram (TIC). The term total ion current chromatogram (TICC) refers to a chromatogram obtained by plotting the total ion detected in each of a series of mass spectra recorded as a function of retention times of the chromatographically separated components of a mixture (which is essentially implicated by: TIC).
I would like to an explanation of the difference between total ion chromatogram (TIC), and total ion current chromatogram (TICC).
