摘要：
Using a VG 9000 glow discharge mass spectrometer, the influence of sample size, sample position, sample shape, discharge current and discharge voltage was studied in detail. The ion intensity signals of elements were not influenced by the sample shape, but were influenced significantly by the sample position, the sample size, the discharge current and the discharge voltage. The maximum ion intensity signals of elements were obtained when the sample was 8-9 mm from the ion exit slit.
