520 | 3 |a“The performance of a Model 212-D Perkin-Elmer Sorptometer has been studied for the measurement of surface areas in the range of specific surface areas between 200 cm2/g and 1000 cm2/g. It was found that, with some modifications to the instrument with regard to the transfer of the desorbed gas from the sample to the detector, the Sorptometer could be used for the surface area measurement of relatively large samples of mineral particles. This Bulletin describes a simplification of the Brunauer–Emmett–Teller (BET) method that can be used for the routine measurement of surface areas on samples of similar characteristics by the one-point determination. The method can be extended to a two-point or a three-point determination in order to obtain a conventional BET plot. A standard procedure is outlined for the calibration of the instrument, for the sample preparation, for the adsorption measurement, and for the calculation of the specific areas"--Abstract, p. i. |
