Abstract
A comparatively simple modification of a standard ion source is descri bed, which allows the measurement of the electron-ionization mass spec tra of small samples of evaporated solids. After this modification, a commercial MI-1201 mass spectrometer can be used for the analysis of m icrogram amounts of high-molecular-mass solids with a saturated vapor pressure of not less than 10(-5) Pa in the temperature interval 300-80 0 degrees C. The possibilities of the modified instrument are demonstr ated by determination of the content of the C-70 C-70 component in C-6 0 fullerite samples of various purity.
