随着社会主义建设事业的发展,近年来我国从国外引进了一些必要的技术装备和科学仪器。分析仪器方面,据了解从日本岛津进口的GC-5A色谱仪的数量是相当大的。其中有不少配有ITG-4AX类型的数字积分仪。该积分仪电路设计上有一定特点,谱峰处理功能也较完善,对一般实际分析基本适用,对仪器制作 With the development of the cause of building socialism, in recent years our country has introduced some necessary technical equipment and scientific instruments from abroad. Analytical instruments, it is understood that the number of GC-5A chromatograph imported from Japan Shimadzu is quite large. Many of them have a digital integrator of the ITG-4AX type. The integrator circuit design has some characteristics, spectral peak processing function is also more perfect, the general practical analysis of the basic application of the instrument
