  • Sampling pumps and closed loop control of sampling pumps to load traps
    Patent number: 11154794
    Abstract: Certain configurations of devices and systems which are configured to draw a selected volume of an air sample into a trap are described. In some examples, the devices and systems comprise a pump and a mass flow sensor to draw a selected volume of the air sample through a trap even where variable restriction occurs.

  • Deconvolution and identification algorithms for use on spectroscopic data
    Patent number: 9640374
    Abstract: A new algorithm is taught for identifying compounds from spectroscopic or mass spectra data, wherein the improved order of operations of the present invention are defined as 1) background noise removal, 2) deconvolution by smoothing peaks, finding peaks and grouping peaks into unknown compounds, 3) preparing correlation values for combinations of unknown compound and target compound pairs, 4) sorting the combinations of unknown compound and target compound pairs by their correlation values, 5) removing complete ions from the mass spectra data using a peak, a retention time, and a retention window, and 6) matching unknown compounds to target compounds such that no target compound appears twice.
