Sentence examples for major fragment observed from inspiring English sources

The major fragment observed for both glucuronides resulted from neutral loss of the glucuronide moiety.

A portion of this mixture (10 μL) was then subjected to UPLC-ESI-MS/MS analysis performed in negative SRM mode using UPLC gradient I by monitoring the transition corresponding to a major fragment ion observed upon CID fragmentation of cross-link 1 in an LTQ mass spectrometer (transitions of m/ z 508 → 392 for cross-link 1 and m/ z 512 →396 for [C3N1]- 1).

The major fragment ions observed in the mass spectra were [M-CH3]+, [M-COCH3]+, [M- CH3 + COCH3)]+, [M- CH3+, [COCH3+ and [COCH3]+.

The loss of 134 Da or C4H6O5 as a major fragment from glucuronides is quite rare and raises two questions: Under which conditions is this fragment formed, or in other words, why was it observed with compound 2 and not by 1 and, secondly, what is the fragmentation mechanism.

The MS spectra of recombinant CFP-10 mapped strong signals for four major fragments, with the two highest signals observed at [M + H]+ 1142.63 and 1593.75 ([M+H]+: protonated molecule) and the other fragments also displayed significant peaks in MS spectra.
