一、前言苏制1301型质谱计是五十年代初的产品,只能用于气体同位素质谱分析。经改装可用1305型质谱计的表面电离源来分析液体形态(固体)样品。但是,由于仪器陈旧,事故多,它的性能和运行效率显然不能适应分析任务的需要,尤其是单带表面电离源与目前盛行的双带或多带源相比,则其不但电离效率低,而且每次涂样装源都很麻烦。同时,按1305质谱计所配置的离子源带的加热部件提供
I. Preface The Soviet model 1301 mass spectrometer is a product of the early 1950s and can only be used for gas isotopic mass spectrometry. The liquid form (solid) samples can be analyzed by surface ionization using a Model 1305 mass spectrometer. However, due to obsolete equipment and accidents, its performance and operational efficiency obviously can not meet the needs of analytical tasks. In particular, the single-band surface ionization source compared with the current double-band or multi-band source not only has low ionization efficiency, And each sample loading source is very troublesome. At the same time, provided by the heating element of the ion source tape configured for the 1305 mass spectrometer
