Webmass-to-charge ratio (m/z) which is insufficient in most practical applications of the technique. For example, more than 1,500 compounds may have the same molecular mass at around 250 Da. Hence, an additional separation technique is needed before presenting the sample to the mass spectrometer. Webhydrogens divided by the charge state (z) of the multiply charged ion distribution. For instance, the mass difference D M between singly, doubly and triply protonated ions clus-ters of PEG and derivatized PEG should be 2(M-1), 2(M-1)/2 and 2(M-1)/3, respectively. The attribution of the charge state was deduced from the mass difference between
