Abstract
A method for automatically calibrating a sensor for a residual gas analyzer includes measuring a known sample by the sensor and obtaining data measurements at a first mass unit. A peak model function is fitted to the data to determine an existence of a peak. The peak model function is aligned to the data using dynamic time warping to determine peak features. It is determined whether a position of a peak center and a peak width are within a predetermined tolerance and, if so, the previous steps are performed for a next mass unit. If the position peak center or the peak width at the first mass unit are outside the predetermined tolerance, a sensor parameter is adjusted and another iteration of the calibration is performed. A signal is issued after a maximum number of iterations has been performed and the peak center and width are outside the predetermined tolerance.
