Adsorbent layer efficiency upon methane elution through Cu3(BTC)2 metal-organic material

Abstract

Methane elution from helium flowing through a sample of Cu₃(BTC)₂ metal-organic framework material has been studied by gas chromatography. The efficiency of a short adsorbent layer has been calculated in terms of a version of the moments method assuming that there are additive contributions to the variance and retention from both the input pulse (or the extracolumn effects) and the processes of substance movement in the flow of the mobile phase through the permeable porous adsorbent. It has been found that the efficiency or the relative length of the layer of the studied metal-organic material sample, as calculated by the moments method, is considerably lower than the values observed for microporous activated carbon.
