Patent number: 11828739Abstract: A method and system for sample analysis involve a temporally-resolving separation of sample components. In the method, solvent vapors are condensed prior to entering a temporally-resolving separator, a GC column, for example, and solvent-depleted vapors are directed to the separator where constituents are resolved in time. A system for analyzing a sample comprises an injection port, a temporally-resolving separator (e.g., a GC column) and a conduit connecting the two. The injection port is at a temperature sufficiently high to vaporize the solvent and analytes present in a sample. The conduit is configured and/or operated to condense the solvent, while maintaining the analytes in the vapor phase.Type: GrantFiled: December 1, 2021Date of Patent: November 28, 2023Assignee: MLS ACQ, Inc.Inventors: Kelly Renee McPartland, Martin L. Spartz

Patent number: 11680894Abstract: A process for identifying an unknown compound in a sample includes matching a peak in a primary Fourier Transform Infrared spectral region of the sample spectrum with reference spectra in the same spectral region to generate an initial list of potential candidates, based, for example on goodness of fit criteria.

Patent number: 10656128Abstract: A method is provided for analyzing a sample and identifying species using chromatography and spectrometry. Possible candidate species to be used in a regression analysis are selected for consideration based on their retention indices in a chromatography column and peak locations in an infrared spectrum. By using such a selection process, the number of combinations of species to be used in the regression analysis can be significantly reduced. The species and respective concentrations in the sample are identified by using an iterative process with regression analysis and minimizing least squares errors between a sample spectrum and a computed spectrum associated with selected candidate species.Type: GrantFiled: April 14, 2017Date of Patent: May 19, 2020Assignee: MLS ACQ, INC.Inventors: Eddie Dean Wyatt, Peter Paul Behnke, Martin L.

Patent number: 10401336Abstract: A sample analysis method includes directing a sample that contains one or more SVOC components to a GC column to temporally separate components present in the sample. Output gas from the GC column is expanded into a sample cell. The sample cell is held at a temperature and pressure that are lower than the temperature and pressure at an outlet of the GC column.
