Vb. Fenelonov et al., DEVELOPMENT OF THE STATE STANDARD SET OF SAMPLES FOR DETERMINATION OFTHE SPECIFIC SURFACE OF CATALYSTS, SUPPORTS, ADSORBENTS, AND OTHER POROUS-MEDIA, Instruments and experimental techniques, 40(4), 1997, pp. 559-562
The State Standard Set of Samples is intended for calibration and atte
station of the adsorption setups and methods for determining a specifi
c surface. The specific surfaces of the standard samples were determin
ed using low-temperature (77 K) nitrogen adsorption isotherms measured
on an ASAP 2400 volumetric setup (Micromeritics, USA) attested as a m
easuring system of the highest accuracy. Examples of comparative tests
performed on various adsorption setups using the standard samples are
considered.
