This paper describes experimental methods and presents results for the adsorption of atmospherically important gases on carbon-based solid adsorbent materials used principally in our on-site ADS-GCMS instruments. We describe two methods for determination of the "breakthrough" of gases through a tube filled with solid adsorbents, this breakthrough can then be used to calculate the retention behaviour of the test gas on the adsorbent material over a wide temperature range, including at below-ambient temperatures. The methods and results described allows the reader to determine whether a particular adsorbent class will be of use in similar or other instrumental systems used for measuring gases in air samples present in extremely low amounts in the atmosphere.
