CO_2激光裂解色谱作为分析不挥发性有机化合物的一种新手段,本刊已有介绍。它的特点是快速、灵敏,裂解谱图简单且重现性较好。本文叙述几种高聚物的CO_2激光裂解色谱工作,并对其定量的重复精度进行初步研究。实验条件 CO_2激光裂解装置:CO_2激光裂解流程同前所述。样品裂解室及送样装置如图1所示。CO_2激光透过锗片密封窗后,聚焦于金属裂解室内的样品上。旋转样品支架能变换样品受激光照射(裂解)位置。CO_2激光器输出功率为20W。
CO_2 laser pyrolysis chromatography as a non-volatile organic compounds analysis of a new means, this article has been introduced. It is characterized by fast, sensitive, simple and reproducible spectrogram. This paper describes the work of several polymer CO 2 laser pyrolysis chromatography, and its quantitative quantitative accuracy of a preliminary study. Experimental conditions CO_2 laser cracking device: CO_2 laser pyrolysis process described earlier. Sample lysis chamber and sample delivery device shown in Figure 1. After the CO_2 laser passed through the germanium sealing window, it focused on the sample in the metal lysis chamber. Rotating the sample holder changes the position of the sample exposed to the laser light (lysis). CO_2 laser output power of 20W.
