  • Quantification of an analyte in serum and other biological matrices
    Patent number: 9209003
    Abstract: Methods and systems for quantifying analytes in a biological sample are provided comprising preparing a biological sample for mass spectrometric analysis, utilizing an ionization source to ionize at least a portion of the prepared biological sample to generate an ionized analyte flow, introducing the ionized analyte flow into a differential mobility spectrometer set at a compensation voltage selected to extract ionized analyte molecules from the ionized analyte flow, introducing an output analyte flow of the differential mobility spectrometer into a mass spectrometer to detect and quantify analyte ions in the output analyte flow.
    Type: Grant
