Thermodesorption is a well known technique for the analysis of volatile organic contaminants in air normally adsorbed on porous polymeres and has been previously discussed [1]. This operation principle can also be adapted for the direct thermal desorption of volatiles in solid samples.
In this paper the potential of a newly developed thermodesorption system for direct desorption and analysis of volatiles from liquid and solid samples is discussed and demonstrated.
It will be shown that the combination of thermal desorption with an intermediate cryofocusing step in the insert liner of a cooled injection system (CIS) is a reliable and fast method for the determination of volatiles within a wide boiling range.
