红外光谱法在仪器分析领域中早已被人们广泛应用,第一代产品是棱镜分光;第二代产品为光栅分光;70年代以后则出现了第三代产品——傅立叶变换红外光谱(FTIR).当傅立叶红外光谱仪与计算机联用后,其灵敏度比第二代产品光栅分光提高了2至3个数谱级.特别是近十年来已发展到了与气相色量仪联用,利用色谱专长的高分离技术,提供有机物基团和化合物结构分析,从而大大提高了它在仪器分析领域中的地位.近几年来我国也引进了不少傅立叶红外光谱仪及界面装置,当与气相色谱联机时,
Infrared spectroscopy has long been widely used in the field of instrumental analysis. The first generation of products is prism spectroscopy; the second generation of products is grating spectroscopy; and the third generation of products - Fourier Transform Infrared Spectroscopy (FTIR) after 70 years. When the FTIR is used with a computer, its sensitivity is improved by 2 to 3 than that of the second generation grating spectroscopy.Especially in the past ten years, it has been developed in combination with a gas chromatograph, utilizing the high chromatographic expertise Separation technology to provide structural analysis of organic groups and compounds, thus greatly improving its position in the field of instrumental analysis.In recent years, China has also introduced a number of Fourier transform infrared spectrometer and interface devices, when coupled with the GC,
