反应气体色谱是一种化学反应和气相色谱相结合的技术,在许多气相色谱专著中都有论述。它能提供官能团的信息,补充光谱和其他结构分析的数据;做色-质分析时,可通过反应色谱消除某些官能团化合物的干扰,使分析更加准确。反应色谱也可用于催化剂的研究。色谱反应器,根据实验时安放的位置大致可分为三类:(一)与分析柱相连接的减除环,或直接用分析柱本身的前后几厘米作为反应器;(二)用汽化室作反应器;(三)预柱反应器,即在色谱系统之前另加一反应器。但是这些反应器不能很好地调温,不能同时得到反应谱图和参比谱图,有气阻差,它们的反应床与整个反应器是一整体,
Reactive gas chromatography is a technique that combines chemical reactions with gas chromatography and is discussed in many GC monographs. It provides functional group information, complements spectra and other structural analysis data, and does color-to-mass analysis to eliminate the interference of certain functional compounds by reaction chromatography, making the analysis more accurate. Reaction chromatography can also be used for catalyst research. Chromatography reactor, according to the location of the experiment can be divided into three categories: (A) with the analytical column connected to the subtraction ring, or directly with the analytical column itself before and after a few centimeters as a reactor; (B) with the vaporization chamber As the reactor; (three) pre-column reactor, that is, before the chromatography system plus a reactor. However, these reactors are not well regulated and can not simultaneously obtain a response spectrum and a reference spectrum with poor gas resistance. Their reaction beds are integrated with the entire reactor,
