在应用数字积分器来测定色谱峰面积的场合、由于色谱基线的波动或偶然的扰动,对积分器来说,将形成假谱峰信号,而使积分器动作、显示或打印出一系列假的峰面积,这是我们所不希望的。下面介绍一种解决这个问题的逻辑线路。 (参阅线路图) 一般说来,假峰面积都是很小的,我们可以事先设定一个峰面积值做为判断真假峰的界限、小于此界限的峰面积就作为假信号的面积,积分器便不进行打印或显示。在图中波段
Where a digital integrator is used to determine the peak area of a chromatogram, a peak or aliquot of the chromatogram will be created for the integrator due to fluctuations in the baseline of the chromatogram or for occasional perturbation, allowing the integrator to operate to display or print a series of false Peak area, this is what we do not want. Here’s a logic to solve this problem. (See Roadmap) In general, the peak area is very small, we can set a peak area value in advance to determine the true and false peak boundaries, less than the peak area of the signal as the false signal area, integral The printer will not print or display.
