Transition metal ion complexes with proteins and peptides are important in many areas of analytical and biological chemistry. We used positive and negative ion MALDI-MS to detect complexes with Cu and Ni ions, and show that the speciรc and non-speciรc transition metal ion-peptide complexes can be di
## Abstract Field desorption mass spectrometry was used to obtain molecular weight information on a variety of transition metal complexes which are air sensitive and nonvolatile. The base peak for the neutral complexes is the molecular ion and for the salt complexes is the cation.
