在色谱分析中,测量半峰宽首先必须确定半峰高的位置。当手工测量的峰数目较多时,一般用三角板量半峰高的位置,不但速度慢,精度也不够高。下面提出三种测量方法,可方便准确快速地确定出半峰高的位置,现简单介绍如下。1.叉规叉规如图1所示,把两根等长的金属片用 In chromatographic analysis, the measurement of half-width must first determine the position of the half-height. When the manual measurement of the number of peaks is more, the general use of the board half the amount of peak height position, not only slow, accuracy is not high enough. The following three proposed measurement methods can be easily and accurately determine the location of the half-height, are briefly described below. 1. Forks and Forks As shown in Figure 1, use two equal length pieces of metal
