红外热成像组合化学分析系统的开发与应用

The Development and Application of A Synthetic IR Thermal Imaging Analysis System

由于红外CCD对温度变化的敏感性,本研究工作设计了一套红外热成像高通量组合化学分析系统。本分析系统的工作原理是利用色谱柱对化学物质先进行分离,分离后的物质由氧载气带入催化剂床进行燃烧,燃烧使催化剂床温度升高,利用IR CCD相机记录温度信号进行分析。这一技术可以同时记录许多信号,实现多样品的高通量分析。本研究工作设计了一个具有8通道的分析系统,以甲醇和丙酮为实例证实了该系统的可行性。

Since IR CCD is sensitive to temperature, a high-pass IR thermal imaging analysis system was built for chemical analysis. The working principle of the instrument is making use of the chromatograph column to separate compounds and bring the separated compounds into combustion catalyst beds by carrying gas oxygen. In the catalyst beds, organic compounds are burned to generate heat and lead to temperature increasing. An IR CCD camera is used to record the temperature increasing information and analyze the composition of samples. Since the IR CCD camera could record information from many samples simultaneously, it is a high-pass technology for chemical analysis. In the current work, an 8-channel parallel analysis system was built, which can analyze 8 samples simultaneously. In this investigation, methanol and acetone were used as probing compounds to verify the instrument.
