现代冶金生产和科研工作,对金属中氢、氧、氮、碳、硫等气体的测试方法,在速度、灵敏度、准确度上均提出了更高要求.以往,为了适应这些要求,曾出现过多种提气方式、分离测定手段、数据处理和程序控制的方法.经过多年的选择淘汰,各国仪器厂家在设计思想上基本趋于一致,所不同的仅仅是在一些局部的考虑上,比如测定器的种类和灵敏度、微处理机的功能、仪器的结构等有所差异.
Modern metallurgy production and research work, on the metal hydrogen, oxygen, nitrogen, carbon, sulfur and other gases testing methods, speed, sensitivity, accuracy are put forward higher requirements.In the past, in order to meet these requirements, there have been A variety of gas extraction methods, separation and determination methods, data processing and program control methods.After many years of selection eliminated, the basic idea of the national instrument manufacturers tend to be the same, the difference is only in some local considerations, such as determination The type and sensitivity of the device, the function of the microprocessor, the structure of the device, etc. are different.
