  • Patent number: 10801930
    Abstract: A method for preparing a sample for chromatographic separation processes, in which a sample vessel is partially filled with a substance to be examined and is closed, is described. The substance to be examined is subjected to a thermo-chemical reaction in which at least one sample component is converted into another substance, and in which by use of a removing device samples are removed from the sample vessel for analytical examination. Also, the sample vessel forms a cavity, into which the substance to be examined is introduced as a core and a heating section for indirect heat transfer is applied along the filling of substance to be examined.

  • Patent number: 10551400
    Abstract: Device for solid-phase microextraction and analysis of substances to be analyzed, in particular in a gas chromatograph, with at least one collector, which is made of sorbent and/or adsorbent 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 piercing the partition wall for a sampling time, wherein the sealing 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 a sealing element onto an upper rim of the sample container, and which comprises a socket in which a fitting of a transport adapter which is attached to a handling end of the rod-like support can be anchored detachably and with sealing surface pressure after the collector is inserted into the sample container following piercing the partition wall.
