These seem to be exorbitantly high, compared with the smallest non-blank standard of 62.5, which gave me a well-behaved chromatogram. My boss wants to know why the LOD and LOQ are what they are compared to the 62.5 ppm standard, and I have no answers for him. I don't know if I'...
Interestingly, performing liquid separations at low pH (by addition of formic or acetic acid) is statistically better since sharper peaks can be obtained on the chromatogram. Formic acid and acetic acid are acid additives that are compatible with mass spectrometry detection, meanwhile, at the same ...
siceraria fruits’ primary metabolome mediating for their nutritive value, GC–MS was employed, leading to the detection of 49 peaks. Chromatograms displayed a representative profile of C. sativus and L. siceraria fruits’ nutrient primary metabolites (Figure S15). Metabolites were categorized into ...
