  • 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: 10367857
    Abstract: A conference call management method, system, and computer program product include inferring an Internet Protocol (IP) address of a new user requesting to join a call including at least one other user, inferring a codec to stream an emulated network pattern for the call if the new user were to join the call, measuring a call quality perceived by the at least one other user in the call while the emulated codec is run on the call, and measuring an impact on the call quality in a case that the new user joins the call based on the perceived call quality and the network pattern.

  • Publication number: 20050032237
    Abstract: The invention relates to a method for solid-phase microextraction and analysis of substances in a carrier fluid, in which a collector is brought into contact with the stirred fluid containing the substances for a sufficient time and is then subjected to a solid-phase extraction directed at at least one substance adhering to the collector, and desorbed substances are transported for analysis by means of a carrier gas, in which the carrier fluid containing the substances is stirred in a receptacle of a magnetic stirrer by means of a coated magnetic stirring element as the collector, and/or the carrier fluid is made to move intimately relative to the collector by means of ultrasound, and then the stirring element is placed in a solid-phase extraction device.
