    摘要: A method is disclosed for operating an electrochemical gas sensor with a measuring electrode pair and a pumping electrode pair. The method includes obtaining a measurement of the interfering species at a location spatially adjacent to a measuring electrode of the measuring electrode pair; and adjusting one or more of an operation or an output processing of the electrochemical gas sensor based on the measurement of the interfering species. In this manner, the measurement of the interfering species may be used to adjust the removal rates of the interfering species and/or to adjust an offset of an analyte measurement to compensate for the presence of the interfering species.

    摘要: The present invention relates to a method for detecting particles and a particle sensor arrangement. More specifically, the present invention relates to a method and arrangement for detecting particles in a gas flow, e.g. from a diesel combustion engine. The method comprises the steps of; forcing a particle build up on a sensor element of a particle sensor arrangement by regulating the sensor element to a second temperature; wherein the second temperature is lower than a first temperature, the first temperature being the gas flow temperature. Additionally is the particle build up detected at the sensor element by means of a detector. The present invention provides for an accurate method and arrangement to detect and thereby measure particles present in a gas flow, e.g. from a combustion engine.
