Table 3: Example of lines in the Expertomica metabolite profiling software PRT report for detected peaks of the MCYSTLR molecular ion of m/z 995 [M + H]+, the sodium adduct ion of m/z 509 , and the molecular ion with cleavage of the Adda moiety ion of m/z 861 [M + 2H − 135]+ for the measurement of MCYSTLR (0.01  g/mL) in Stigeoclonium sp. extract. The MCYSTLR molecular ion was detected with a probability factor of 0.952 (95.2% of the analyte signal). Expertomica metabolite profiling software also reports the relative content of the MCYSTLR molecular ion in the whole measurement, the values of the peak borders (start time and end time) in the time axis as well as the time of maximal intensity (RT), value of that maximal intensity, and peak area.
