In all cases, the correct charge states could be determined. The obtained absolute mass errors were in a range between −0.2 and 1.2 Da, the relative errors below 30 ppm. NettetWhat Is An Intact Mass Analysis? Intact mass analysis is the measurement of a protein's total molecular weight by mass spectrometry (MS) without prior digestion or fragmentation of the molecule of interest. The observed mass can then be compared to the expected mass for a given amino acid sequence. Intact mAb Mass Check Standard route stores
