Patent number: 9453765Abstract: A method in which the wavelength of the light of a tunable light source is varied periodically over an absorption line of interest for the gas component to measure the concentration of a gas component in a measurement gas based on one of two measurement methods of direct absorption spectroscopy and wavelength modulation spectroscopy and, where in the case of wavelength modulation spectroscopy, the wavelength of the light is additionally sinusoidally modulated at a high frequency and with a small amplitude, where the intensity of the light is detected after transradiation of the measurement gas and processed to yield a measurement result, and where in order to increase the accuracy and reliability of the measurement, the two measurement methods are applied simultaneously during each period, or alternately in consecutive periods, and their results are combined by averaging to form the measurement result.Type: GrantFiled: December 19, 2013Date of Patent: September 27, 2016Assignee: Siemens AktiengesellschaftInventors: Daniel Depenheuer, Thomas Hankiewicz, Frank Probst

Patent number: 9347921Abstract: Low-complexity, application-independent fixation of a chromatogram is achieved by a) determining a limit frequency under the assumption that the shape of the peaks in the chromatogram corresponds approximately to a Gaussian function having a standard deviation and the Fourier transform of the Gaussian function describes the frequency spectrum of a peak, at which limit frequency the Fourier transform has decreased to a predetermined limit value, b) determining the height, width, and retention time of each individual peak from the chromatogram, or a chromatogram taken previously under the same conditions, c) determining a constant factor based on a first predetermined relationship, d) determining the functional dependency of the limit frequency on the retention time as a variable quantity based on a second predetermined relationship, and e) filtering the chromatogram with the limit frequency depending on the retention time as the variable quantity using a low-pass filter.Type: GrantFiled: July 29, 2010Date of Patent: May 24, 2016Assignee: Siemens AktiengesellschaftInventor: Frank Probst

Patent number: 9267907Abstract: A measurement arrangement includes four electrically heated resistors which are arranged in gas paths and are connected to form a Wheatstone bridge, where each of two resistors which are diagonally opposite each other in the Wheatstone bridge are contained in a respective component arranged on a common heated carrier, each respective component is assigned to one heating resistor arranged near the component on the carrier, and where an unbalanced state of the Wheatstone bridge is compensated for by variably energizing the heating resistors.Type: GrantFiled: January 18, 2012Date of Patent: February 23, 2016Assignee: Siemens AktiengesellschaftInventors: Frank Probst, Josef Richter

Patent number: 9116160Abstract: 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.Type: GrantFiled: November 25, 2010Date of Patent: August 25, 2015Assignee: Siemens AktiengesellschaftInventors: Udo Gellert, Frank Probst

Publication number: 20140060152Abstract: Method for chromatographic analysis of a hydrogen-containing gas mixture, wherein a first dose of the gas mixture is guided through a separation device using helium as a carrier gas during a first measurement pass and concentrations of separated components are measured, the concentration of the hydrogen in the gas mixture is measured and the measurement value is obtained up to an upper limit value in the range from 5% to 6%, and a second dose of the same gas mixture is guided through the separation device using the same carrier gas during a second measurement pass, wherein as compared to the first measurement pass the dose is reduced, the gas mixture is volumetrically diluted and/or the carrier-gas speed is reduced, and the hydrogen concentration is re-measured, and the measurement value obtained during the first measurement pass is verified against the measurement value obtained in the second measurement pass.Type: ApplicationFiled: March 29, 2012Publication date: March 6, 2014Inventors: Frank Probst, Piotr Strauch

Publication number: 20120131987Abstract: 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.Type: ApplicationFiled: December 9, 2009Publication date: May 31, 2012Applicant: Siemens AktiengesellschaftInventors: Udo Gellert, Frank Probst
