The Micrometrics Tristar® II 3020 analyzer allows the determination of surface area, pore volume, pore size distribution (and many other parameters) of solids through the obtention of nitrogen adsorption/desorption isotherms at -196 ºC. For this purpose, the sample must be previously degassed in order to avoid the desorption of gases or vapors during the analysis. In this way, the LRC carries out a systematic thermal treatment under vacuum or nitrogen flow prior to the analysis, depending on samples’ requirements. For this reason, it is mandatory that the user provides detailed information on the sample’s thermal stability in order to avoid any decomposition inside the sample holder. The average amount of sample required for the analysis is 200 mg, however, 500 mg of the sample is strongly recommended in case the analysis needs to be repeated for any reason.
PS: once the analysis is done, the results are sent by email and the samples can be recovered since the analysis is not destructive.
