  • Publication number: 20210003461
    Abstract: A method and apparatus are disclosed for calibrating a first sensor in a changing operating environment by a calibration process. Sensor data are received from the first sensor and sensor values are received from a known calibrating sensor. A sensor specific model is maintained for the first sensor. Calibration needs are detected by estimating a drift and an error, taking into account a difference of sensor values to the known calibrating sensor and further taking into account a sensor profile of the first sensor. A correction factor or a correction model is estimated to the sensor data using said difference and used for calibrating the sensor. The correction factor or the correction model is derived from the sensor specific model.

  • Publication number: 20140302616
    Abstract: Properties, such as concentrations, of gas phase bases or acids of a gas sample are determined by providing a sample gas flow, which includes the bases or acids to be determined as sample constituents, as well as also interfering constituents, which are other constituents than the sample constituents. Reagent ions are provided and introduced into the sample gas flow to arrange proton transfer reaction and thereby forming sample ions. Also a dopant is introduced into the sample gas flow to arrange proton transfer reaction between the dopant and the interfering ions thereby forming dopant ions and electrically neutral interfering constituents. For determination the gas flow with the sample ions to be determined is introduced together with the dopant ions to a mass spectrometer in order to determine the properties of the gas phase bases or acids.
