13. Time data are printed above the peak maxima in each ot the ion chromatograms and in the UV trace shown in the bottom panel. Note that the UV trace is 10-12 s ahead of the peaks shown in the ion chromatograms. This time difference is the delivery time between the split in the HPLC leading to the ion source of the mass spectrometer.
