三、检测技术在气相色谱仪的发展中,检测器的研制,是最主要的一个环节之一。近年来超纯气体的需要,尖端技术的发展,高分子材料合成中对痕量杂质的控制以及公害防治等,对检测器提出了极高的灵敏度、选择性、定性和定量分析性能方面的要求,这就促进了检测器的迅速发展。许多物理和物理化学方法都被用到气相色谱上制成各种检测器。但是对一个检测器的评
Third, the detection technology In the development of gas chromatograph, the detector of the development is one of the most important part. In recent years, the need for ultrapure gas, the development of cutting-edge technologies, the control of trace impurities in the synthesis of polymer materials, and the prevention and control of pollution have provided highly sensitive, selective, qualitative and quantitative analytical requirements for the detector , Which promotes the rapid development of the detector. Many physical and physicochemical methods are used to make various detectors on a gas chromatograph. However, the evaluation of a detector
