摘要：
It is demonstrated by comparing the mass spectra of cesium iodide cluster ions obtained under different operating parameters that such factors as acceleration voltage, system pressure, and primary beam energy affect the high-mass signal current to a greater extent than that of the low mass. The measurements imply that consideration should be given to these parameters for more effective analysis of high-mass compounds.
