Abstract: The invention relates to a gas sample to be analyzed, wherein said sample is guided by means of a carrier gas through a separator unit having a downstream thermal conductivity detector providing a chromatogram having peaks for different analytes as a measurement signal. When using a thermal conductivity detector having a heated gold thread coated with a parylene F, hydrogen is used as a carrier gas, and a peak for the analyte hydrogen sulfide is generated by differentiating the chromatogram at the location of said analyte. The invention permits unlimited use of hydrogen as a carrier gas, even if the analyte is oxygen.

Abstract: An arrangement for metering a gaseous sample in a carrier gas stream has a sample gas path and a carrier gas path, both paths being connected to a carrier gas source. By introducing different pressures into the sample gas path and the carrier gas path, a metered amount is extracted from a sample slug and diverted into the carrier gas stream via a connection gas path through the carrier gas path. The sample gas path has two flow resistances in front of and behind a branch point of a connection gas path. One resistance lies between the carrier gas source and a metering unit and a gas volume of the sample gas path between the branch point of the connection gas path and the other flow resistance is dimensioned such that the sample slug only reaches the second resistance after extraction and diversion of the metered amount.

Abstract: A separation-column unit includes a support plate having a groove formed therein on one side and running, for example, in the form of a spiral, and having a cover plate which bears against this side. In order to achieve the high separation capacity combined with a high load-bearing capacity with regard to the amount of sample flowing through, the depth (d) of the groove is preferably at least three times greater than its width. The base of the groove preferably has a rounded cross section, it being possible for the cover plate to contain a corresponding channel.

Abstract: A method for analyzing a gas mixture through gas chromatography, wherein a sample of the gas mixture is fed to a dosing volume using a metering valve in a first valve position and, in a second valve position the sample of the gas mixture is fed from the dosing volume through a separating device by a carrier gas. A gas component of interest, arriving at the separating device and separated from the sample, is detected by a detecting device. Part of the separating device and the metering valve are flushed with another carrier gas after the gas component of interest has passed through a part of the separating device to facilitate a precise gas chromatography analysis using minimal technical effort. Another gas sample is then fed from the dosing volume to the separating device using the other carrier gas.

Abstract: A thermal conductivity detector with an electrically heatable heating filament (6) that is mounted in the middle of a channel (5) in such a way that a fluid can flow around it. The heating filament is carried on its two ends on two electrically conductive carriers (7, 8) that intersect this channel. In particular to prevent the heating filament from relaxing at operational temperatures, at least one of the two carriers (7, 8) is embodied in such a way that its distance from the other carrier is greater in the region of the middle of the channel than in the region of the wall of the channel (9). As a result, as the temperature rises, the middle areas of the two carriers (7, 8) on which the heating filament (6) is held move away from each other, so that the heating filament (6) is tightened.
