Claims17
A collector for the microextraction and analysis of substances to be analysed, comprising a layer which includes a first collector material of at least one material of the group consisting of a sorbent and adsorbent material, the interior of which forms a receiving space with a filling of a second collector material of at least one material of the group consisting of a sorbent and adsorbent material encapsulated therein is provided, the second collector material having a different selectivity from the first material, the layer being permeable to the substances which can be sorbed and adsorbed, respectively, by the second collector material, and the filling being at least partially covered with respect to the outside by the first collector material wherein the filling has a higher selectivity with respect to highly volatile components of the substances to be analysed than the covering layer.
