紫外和可见光吸收检测器是目前HPLC使用最广泛的检测器,特别是254mm固定波长紫外检测器,结构简单,使用方便,售价便宜,使用更加普遍。但它只有一个固定的检测波长,使应用范围受到很大限制。多波长和可变波长检测器克服了固定波长检测器的缺点,能为化合物的检测提供更多供选择的波长。自动扫描检测器则有更大的优越性,它既可提供色谱图,又可提供光谱图,能为化合物的鉴定提供定性资料,其缺点
UV and visible light absorption detector is currently the most widely used detector of HPLC, especially the 254mm fixed wavelength UV detector, simple structure, easy to use, the price is cheap, the use of more common. However, it has only a fixed detection wavelength, so that the application range is greatly limited. Multiwavelength and variable wavelength detectors overcome the disadvantages of fixed wavelength detectors and provide more wavelengths for the detection of compounds. Automated scanning detector has greater advantages, it can provide both chromatograms, but also provides the spectrogram, can provide qualitative information for the identification of compounds, the shortcomings
