Ion mobility spectrometry combined with highresolution mass

A direct solution analysis method, cold-spray ionization (CSI) mass spectrometry (MS), a variant of electrospray (ESI) MS operating at low temperature (ca -80 to 10 degrees C), allows the facile and precise characterization of labile organic species, especially those in which non-covalent bonding interactions are prominent.

The mass spectrometry data for Rivularia sp. cyanobacteria were deposited at MassIVE (accession no. MSV000085578). The spectra for rivulariapeptolide 1155 were annotated in the GNPS spectral.

CSI-MS is also used to investigate the behavior of aggregated steroid compounds, namely, bisguanidinobenzene-benzoic acid complexes, in solution. This method is a powerful tool for analyzing the equilibria of multiply linked self-assembling catenanes in solution. Its application to unstable and complex supramolecules will be shown.

A simple method for measuring CsI cluster ions ((CsI) n Cs + and (CsI) n I −) from CsI 3 for mass calibration was developed using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). The application of CsI 3 with an additive, sugar alcohol (e.g., glycerol) or saccharide (e.g., dihydroxyacetone), on the MALDI plate resulted in an adequate series of CsI cluster ions within.

Cold spray ionization mass spectrometry (CSI-MS) is a variant of ESI-MS that promotes ionization by increasing the polarizability of the compound at low temperature [17]. This native-MS technique allows the facile and precise characterization of weak noncovalent interactions in solutions compared to the conventional ESI method [18].
