Abstract
Tenax tubes are adsorbent cartridges commonly used in Gaschromatographic (GC) analyses with preconcentration purposes. Thus many devices are commercially available to desorb tenax tubes into the GC inlet. The use of tenax tubes as sampling medium is also suitable for the analysis of volatile mixture with gas sensor arrays. This application rises up an interface problem which is faced by the present work with a desorption device designed and calibrated on the basis of theoretical models. These models are calculated on the characteristics of selected volatile compounds present in the exhaled breath. In fact, tenax tubes could be of main interest in breath analysis.
