Sentence examples for mass errors for from inspiring English sources

The software performs automatic recalibration such that typical mass errors for MS and MS/MS data were below 10 ppm.

Despite the fact that this low abundance variant represents only 0.70%% of total peak area (see Fig.  3a), all diagnostic fragment ions as well as the intact mass of the protein were detected, albeit with higher mass errors for the low intensity fragments.

When the above techniques are applied simultaneously, the results give rise to sub-30 ppb rms mass error for 5250 assigned peaks in a petroleum FT-ICR mass spectrum.

mass error of each single spectrum 2000; desired mass error for the MSP 200; desired peak frequency 25%%; max.
