Peptides
and Proteins
This spectrum shows the signal from a four-fold charged peptide A of mass 3853.87 amu.
The mass resolution is 20000 (FWHM)
This is a complete spectrum of
peptide B.
It shows the 3-, 4-, and 5-fold
charged monomer, and the 7-,
8-, and 9-fold charged dimer of this peptide.
This spectrum shows the 4-fold
charged monomer of peptide B above the 8-fold
charged dimer.
This spectrum shows the alpha-
and beta- chain of hemoglobin (bovine),
the insert shows the
isotopic distribution of the 13+ charge state.
