§1 引言用色谱法测定多孔固体的比表面和孔径分布是研究固体催化剂、吸附剂性质的常用手段之一。处理实验数据的第一步是准确测量记录仪绘出的色谱峰峰面积。国内生产的ST—03表面及孔径测定仪测出的峰是不对称的色谱峰(如图1)。由于条件限制,目前多数实验室内主要以手工测量其面积S。常用的方法是手工测其峰高峰宽代入公式(1) § 1 Introduction Chromatographic determination of porous solid specific surface area and pore size distribution is one of the common means to study the properties of solid catalysts and adsorbents. The first step in processing the experimental data is to accurately measure the chromatographic peak area plotted by the recorder. Domestic production of ST-03 surface and aperture detector measured peak asymmetric peaks (Figure 1). Due to the limited conditions, most laboratories mainly measure the area S by hand at present. Commonly used method is to manually measure the peak peak width into the formula (1)
