On the calibration of the catharometer in determining the specific surface area of solids by the chromatographic method of thermal desorption

Abstract

When determining the specific surface area of solids by the gas chromatographic method of thermal desorption, the areas of desorption calibration peaks are compared. The catharometer is usually calibrated by introducing an adsorbate gas into the main stream. Another gas, such as air, can also be used for this purpose...
