  • Publication number: 20070136017
    Abstract: A method for obtaining at least one calibration filter for a Mass Spectrometry (MS) instrument system. Measured isotope peak cluster data in a mass spectral range is obtained for a given calibration standard. Relative isotope abundances and actual mass locations of isotopes corresponding thereto are calculated for the given calibration standard. Mass spectral target peak shape functions centered within respective mass spectral ranges are specified. Convolution operations are performed between the calculated relative isotope abundances and the mass spectral target peak shape functions to form calculated isotope peak cluster data. A deconvolution operation is performed between the measured isotope peak cluster data and the calculated isotope peak cluster data after the convolution operations to obtain the at least one calibration filter. Provisions are made for normalizing peak widths, combining internal and external calibration, and using selected measured peaks as standards.

  • Publication number: 20070046933
    Abstract: In a spectroscopic process a sample for producing a test spectral line or spectrum of at least one component contained in the sample is stimulated and the transmitted and/or emitted electromagnetic rays are used to create the test spectral line or spectrum. In order to improve such a spectroscopic process to such an extent that variations of certain parameters, which alter the shape and/or occurrence of a spectral line, are compensated, a comparison spectral line or spectrum of a known comparison material is produced under substantially the same parameters as the sample. The comparison spectral line or spectrum is compared with an ideal comparison spectral line or spectrum in order to calculate a transfer function, and the transfer function is applied to the test spectral line or spectrum in order to calculate a corrected test spectral line or spectrum.

  • Publication number: 20060088444
    Abstract: In a luminescence detecting apparatus and method for analyzing luminescent samples, luminescent samples are placed in a plurality of sample wells in a tray, and the tray is placed in a visible-light impervious chamber containing a charge coupled device camera. In the chamber, light from the luminescent samples pass through a collimator, a Fresnel field lens, an infrared filter, and a camera lens, whereupon a focused image is created by the optics on the camera. The use of an infrared filter suppresses stray IR radiation resulting from plate phosphorescence (which can result in abnormally high backgrounds and/or alteration of the image received by the camera).
