Abstract

PURPOSE:To improve SN ratio and sensitivity by using charge coupling elements as minute detector arrays and carrying out charge transfer in relation to charge coupling elements simultaneously with sweeping the mass number. CONSTITUTION:Sample ions 2 generated in an ion source 1 are dispersed with a double focusing mass analyzing system according to the mass-charge ratio and jetted into the charge transfer element (CCD)7 through a channel plate 5. Charge transfer is effected on CCD7 simultaneously with sweeping the spectrum on the channel plate 5. The signal taken out of the CCD7 is transferred to a computer 19 through a A-D converter 18.
