本文第一部分介绍了气相色谱仪和付立叶变换红外光谱仪接口的设计原理和结构,结合应用实例叙述了使用计算机技术,提高了色谱分离度,提高了红外信噪比,同时提高了收集分离组份,红外图谱自动检索的自动化程度。样品最小检出量为10ng。第二部分介绍了高效液相色谱仪和付立叶变换红外光谱仪接口。一是以美国Nicolet公司为代表的微量流动池,用差示光谱技术测量;二是以美国Digilab公司为代表,将样品收集后,挥发掉溶剂,用漫反射技术进行测量。着重叙述了漫反射技术的
The first part of this article introduces the design principle and structure of the gas chromatograph and the Fourier transform infrared spectrometer interface, combined with practical examples described the use of computer technology to improve the chromatographic resolution and improve the infrared signal to noise ratio, while improving the collection of separation group The automatic degree of automatic retrieval of infrared spectra. The minimum detectable amount of sample is 10ng. The second part introduces HPLC and Fourier transform infrared spectroscopy interfaces. The first is the micro flow cell represented by Nicolet Company in the United States, which is measured by differential spectroscopy. The second is the measurement by the United States Digilab company. After the samples are collected, the solvent is volatilized and measured by diffuse reflectance technique. Focus on the description of diffuse technology
