Device for solid-phase microextraction

A device for solid-phase microextraction and analysis of substances to be analyzed, with at least one collector, which is made of sorbent material and is placed on a rod-like support, and with at least one sample container, which is sealed with a pierceable partition wall and into which the collector is introduced by piercing the partition wall for a sampling time, the sealing by means of the partition wall is designed to be leaktight to fluids, wherein the seal of the sample container is assembled from the pierceable partition wall and a clamping ring, which can be mounted on the sample container and presses the partition wall together with an insertable sealing element onto an upper rim of the sample container, and wherein the seal comprises a socket secured between the clamping ring and the upper rim of the sample container, wherein a fitting of a transport adapter can be detachably anchored within the socket with sealing surface pressure after the support lined with a collector and being used as a piercing member is inserted into the sample container following piercing the partition wall, wherein the transport adapter is attached to a handling end of the rod-like support.
