We suggest a technique for preparing nanoporous samples with adsorbed gas for the spectrometric experiments, which allows one to determine the concentration of the absorbed sample gas molecules using a buffer chamber of a large volume in the vacuum system. We also suggest a method which allows a decrease in the sample cleaning time from the absorbed molecules by about an order of magnitude comparing with the sample cleaning time at a room temperature using simultaneous pumping and contactless gas sample heating by radiation of a halogen lamp.
The technique and the method tested in simple laboratory experiments of water vapor sorption by silicon (SiO2) airgel.
