日本的质谱技术起步较早,但早期的进展缓慢,所用仪器多数来自美国。60年代初期以来,日本的质谱仪器生产有了飞速发展,不仅在很大程度上满足了本国的需要,而且有相当数量的出口。本文拟就日本主要质谱仪器生产厂家的产品(见表1)作一简单评价,以利借鉴。日立公司日本第一家质谱仪器生产厂——日立制作所于1943年开始研制质谱计,1950年推出第一台产品,此后10年,向国内提供了约60 Mass spectrometry technology in Japan started earlier, but its early progress was slow. Most of the instruments used were from the United States. Since the early 1960s, the rapid development of mass spectrometry equipment in Japan has not only largely satisfied the needs of its own country, but also has a considerable amount of exports. This article is intended to make a simple assessment of the products of major mass spectrometer manufacturers in Japan (see Table 1), in order to facilitate reference. Hitachi Ltd. Japan’s first mass spectrometer equipment factory - Hitachi Manufacturing Co., started in 1943 to develop a mass spectrometer, launched in 1950 the first product, then 10 years to provide about 60
