Themassspectrumof the daughter ions is recorded by sequentially ejecting the product ions with a mass-selective instability scan.
From theCambridge English Corpus
If we seek to identify background phenomena responsible for the seedmassspectrumdifferences, the following effects should be considered.
From theCambridge English Corpus
Tentative compound identifications were performed according to themassspectrumlibrary and correspond to the best fits to known mass spectra (fit factors > 90%).
From theCambridge English Corpus
Themassspectrumreflected ions corresponding to the molecular weights of the oligomers which were expected to be produced from the mixture of alkylamino acids.
From theCambridge English Corpus
The detector also records the relative abundance, which is plotted against the m/z value to give themassspectrum.
From theCambridge English Corpus
Compounds are named after tentative identifications according to themassspectrumlibrary (fit factors > 90%).
From theCambridge English Corpus
Complicated ions were observed in themassspectrum.
From theCambridge English Corpus
The different amounts of extension products resulting from the nonmutant (filled peak) and mutant (open peak) alleles are reflected in themassspectrumby their different peak heights.
From theCambridge English Corpus
This notation is not uncommon in the physics of mass spectrometry but is rarely used as the abscissa of amassspectrum.
