| titleOfInvention | Methods for calibration of a quadrupole mass filter |
| abstract | The linear relationship between physical mass-to-charge ratio and the location of a mass spectral peak along the DC/RF scan line of a quadrupole mass filter is used to simultaneously identify a known set of calibrants and to determine the correct slope and scaling of the scan line from a full spectrum scan of an uncalibrated instrument. This is achieved by using a method for image feature detection, to find a set of collinear peaks in a two-dimensional image constructed from scaled versions of the mass spectrum. The method for feature detection may include a Hough transform, Radon transform or other machine-vision technique. |
