Mass Spectrometry Facility CI
Coldspray ionization (CSI) mass spectrometry (MS) has been developed and applied to characterize labile organometallic compounds. While conventional ESI is not applicable to those compounds because of their instability to heat and/or air, CSI affords multiply charged molecular ions with many solvents molecules attached. Here we describe the CSI method and its application to several labile.

Applications of Mass Spectrometry
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.
Effective methods for the measurement of CsI cluster ions using MALDI
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].
