An application of C₆₀-assisted laser desorption/ionization mass spectrometry of two organic samples including insulin (5734 Da), bovine albumin (66 000 Da) and a heteropoly inorganic system: phosphotungstic acid H₃PO₄(WO₃)₁₂×H₂O, is presented. A nitrogen laser (337 nm) on a linear tandem time-of-flight mass spectrometer is used for the observation of the laser-power dependence of mass spectra.
