MALDI-TOF/TOF 串联质谱仪
Proteomics groups sequencing peptides and mapping phosphorylation or glycosylation need MS/MS on MALDI spots. This TOF/TOF selects precursors from m/z 700–4000 in a 1–3 u window, gives fragment resolution of about 1500 FWHM and fragment accuracy of ≤50 ppm. MS resolution is at least 15000 FWHM. Sensitivity reaches ≤50 fmol for Glu-fibrinopeptide in MS/MS.
