Abstract

The ion formation characteristics of seven palladium complexes and coordination compounds were analyzed using electrospray ionization (ESI) and ion trap mass spectrometry (ITMS). It was observed that ligands having a single negative charge could undergo interchange with a mobile phase solvent molecule. It was found that lithiated molecule ions could be only be generated when the ESI needle was in line with the capillary entrance aperature of the ion trap. The results suggest that most of the cationized molecule ions are being formed in the gas-phase by collisions with lithium ion clusters and neutral complexes in the gas phase.
