  • Method For Determining Gas Concentrations in a Gas Mixture Based on Thermal Conductivity Measurements With Correction of Measured Values
    Publication number: 20120073357
    Abstract: A method for the determination of gas concentrations xi in a gas mixture using a thermal conductivity detector with a Wheatstone bridge. It comprises the following method steps: measuring the bridge voltage Xa; correcting the measured values for the bridge voltage Xa, in particular with respect to drift; determination of the thermal conductivity of the gas mixture; and determination of at least one gas concentration xi. Preferably, an automatic zero-point correction and an automatic measuring range end value correction occur within the framework of the correction.
