Figure 5. Comparison of ions intensities of the precursor ion m/z = 905.4727 and it fragmental at different accelerating voltage (CAV) values. Arrows show the tracing of fragment ions y7 and y4. Intensity and order the fragment ions at CAV = 5 В. Figure shows the following order of decreasing intensities: y7 (m/z = 925.4778), y4 (m/z = 597.3031) and b5 (m/z = 545.2566) (А). At CAV equal to = 3.5 V we observe the same order of the fragmental ions with slightly decreased y4 fragment intensity (B). At CAV equal to = 2 V we observe the same order of the fragmental ions with the higher degree of decreased intensities(C). Dependence of relative intensities of fragment ions of the peptide precursor ion m/z = 905.4727 on CAV (D).
