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.
