The base peak
at m/z 545 corresponding to the loss of 30 u (methoxy group) from fragment ion at m/z 575 was indicative of the presence of a methyl group on the flavone moiety (chrysoeriol) in compound 5.
Figure 3 shows the sample base peak
chromatogram of the grains of winter wheat variety Anthus.
The mass spectral data recorded an odd number base peak
at 163 M/Z for a compound whose molecular weight was observed at 194 M/Z.
45 minutes and has an intensity that is less than 15% relative to the base peak
in the same spectrum.
The specific ions monitored were base peak
Q1 (mass m/z); Q3 mass (product ions m/z): PFOS (Q1, 499.
In the base peak
oil scenario, it takes 10 years--from 2014 to 2024--for a drop of that magnitude (0.
The largest peaks in each cluster represents to mass number 183 whose base peak
is considered to be 100%.
