It was noteworthy that the proportion of variant base peak
was similar to that of differential site on exon 7 [Figure 6] and [Supplementary Figure 2 [SUPPORTING:2]].
The spectra of all the formulated compounds showed molecular ion peak as the base peak
as well as it was the most stable fragment produced.
The molecular ion peak is denoted by value in bold while the italic value refers to the base peak
. Mass spectra of all compounds from 3a-8a gives base peak
at 232 m/z that was originated by the cleavage of phenyl ring from the original molecule and matched the testified standard value.
Figures 2 and 3 show base peak
For the strongest peak in each mass spectrum (the "base peak
"), the 95% uncertainty intervals are probably also reliable, but for other peaks, the 95% intervals may be too narrow .

It is observed that the molecular ion of ethanol (mass 46) is in fact not the most significant peak and typically mass 31 (the CH20[H.sup.+] fragment ion) is selected as the base peak
for ethanol calibration.
MRIC of each cellulosic materials characterized by area at different retention time and each area has a fixed base peak
(100%) in mass spectra that is characterized to monomer cellulose and cellulose xanthate.
A 6-C-pentosyl-8-C-hexosyl substitution was indicated for compound 3, due to the increased abundance of the fragment ion at m/z 489 (base peak
), in relation to the fragment ion at m/z 459, according to Lin and Harnly (2010).
Figure 3 shows the sample base peak
chromatogram of the grains of winter wheat variety Anthus.
The observation of the base peak
of nerolidol resulting from the loss of water is consistent with other reports.
The mass spectrum showed a peak at m/z 254 (M + [H.sub.2]O, 5%) with a base peak
