Abstract

An arrangement (100) for detecting atoms and/or molecules desorbed from at least one sample, the arrangement comprising at least one desorption chamber (102) adapted to keep an ultra-low pressure, wherein the desorbed atoms and/or molecules may be detected by heating the sample in the desorption chamber (102). The arrangement additionally comprises a cooling system (106) for cooling the sample prior to the heating of the sample.
