Kooijman, Pieter C. published the artcileA novel dual ionization modality source for infrared laser ablation post-ionization mass spectrometry imaging to study fungicide metabolism and transport, Computed Properties of 1885-29-6, the main research area is ionization modality IR laser ablation postionization MSI fungicide metabolism.
We present a novel probe design for ambient laser-based mass spectrometry imaging combining electrospray ionization (ESI) and atm. pressure chem. ionization (APCI) in a single probe, compatible with a com. laser ablation electrospray ionization (LAESI) instrument. Here we describe the probe design considerations and features, as well as an inhouse developed data processing routine designed to extract accurate mass spectrometry imaging data from ambient laser ablation post-ionization experiments We characterize the probe performance in both APCI and ESI mode on a selection of compounds and show improved pixel-to-pixel repeatability for LA-APCI as compared to LAESI. We apply the dual ionization probe in APCI mode in a time series experiment to monitor agrochems. on tomato plants. We investigate the translocation of fungicide isotianil and one of its metabolites, anthranilonitrile, by mass spectrometry imaging over a period of two weeks after application on a leaf surface. LA-APCI-MSI shows translocation of anthranilonitrile from treated leaves towards non-treated leaves. In summary, we demonstrate that LA-APCI imaging is a valuable addition to the ambient mass spectrometry toolbox, with particular advantages for imaging experiments across a variety of compounds
