  • Publication number: 20220236154
    Abstract: The present invention is a system and method for improving extraction of analytes from a solution by disposing a plurality of polydimethylsiloxane(PDMS) particles in a thin layer on an inner wall of an extraction vial, by increasing a surface area and volume of particles disposed to extract analytes from the solution and thereby increasing extraction capacity and speed for gas chromatography-mass spectrometry (GC-MS) analysis.

  • Patent number: 10859545
    Abstract: A system for providing standard mixtures of volatile and semi-volatile organic compounds for simultaneous GC and MS calibration in a calibration vial, wherein calibration mixtures are prepared by diluting calibration analytes in granular PDMS such that most of the analytes are in the PDMS phase and the sample can then be taken from the analytes in the headspace vapor in the calibration vial, wherein a reliable calibration sample can be taken from the calibration vial because the analytes in the PDMS phase and the headspace vapor are in thermodynamic equilibrium, and wherein the method provides solvent-less sampling, long-time stability, ease of use, is quantifiable, and related to temperature.

  • Publication number: 20180217034
    Abstract: A rugged SPME system and method for up-taking analytes, allowing injection of liquid samples in the field, providing better quantitation and reproducibility, and having higher capacity than other SPME devices that use a fiber, wherein the embodiments include a SPME stainless steel coiled wire sampler that may wick a liquid sample into the coil to thereby deliver a consistent quantity of liquid to an analyzer.
