Analysis of Coordination and Organometallic Compounds Using Photoionisation Mass Spectrometric Techniques

Abstract

Abstract A range of coordination and organometallic compounds have been analysed by quadrupole ion‐trap mass spectrometry using various photoionisation methods. Atmospheric‐pressure photo ionisation (APPI), which combines atmospheric‐pressure chemical ionisation (APCI) with a photolysis lamp, was compared with the new technique photo‐assisted electrospray ionisation (PAESI). Additionally, the atmospheric‐pressure matrix‐assisted laser desorption ionisation (AP‐MALDI) was also evaluated and compared to MALDI quadrupole ion‐trap time‐of‐flight (MALDI‐QIT‐TOF) mass spectrometry.
