从记录仪中得出的检测峰不是真实的色谱峰,而是流出峰在流通池内受检测过程影响后所得出的。本文推导了检测峰与流出峰的数学关系,指出检测峰是流出曲线与检测器特性函数(DCF)的卷积,可用快速富里叶变换或专门程序由检测峰得出流出峰,这有利于进行理论研究并可在此基础上建立两种快速的定量法——紫外分光吸收系数法和流出峰法。本文首次提出检测器特性函数的概念。 The detected peak from the recorder is not a true chromatographic peak, but the peak of the outflow peak in the flow cell resulting from the detection process. This paper deduces the mathematical relationship between the detected peak and the outflow peak, and points out that the detected peak is the convolution of the outflow curve and the detector characteristic function (DCF). The outflow peak can be obtained from the detected peak by fast Fourier transform or special procedure, Theoretical studies and based on this two fast quantitative methods - UV absorption coefficient method and outflow peak method. This paper presents for the first time the concept of detector characteristic function.
