  • Patent number: 10545077
    Abstract: The present disclosure provides an extraction coating for an SPME sampling instrument, where the extraction coating includes a sorptive material immobilized in a fluorocarbon polymer that is compatible with thermal-assisted desorption techniques, solvent-assisted desorption techniques, or both. The disclosure also provides SPME sampling instruments, methods of making an SPME sampling instrument, and methods of extracting an analyte from a sample matrix using the SPME coating.
    Type: Grant
    Filed: March 1, 2017
    Date of Patent: January 28, 2020
    Assignee: JP SCIENTIFIC LIMITED

  • Patent number: 10545073
    Abstract: The present disclosure relates to a method and a solid phase microextraction sampling instrument for inserting into or through a solid or semisolid material to extract a component of interest from a sample, comprising a support structure at least partially coated with an extraction phase for extracting the component of interest, a protrusion that shields the coating during insertion, where the distances within a cross-sectional plane of the sampling instrument are greater than or equal to the corresponding distances in all of the cross-sectional planes located between the cross-sectional plane of interest and the insertion end of the sampling instrument. The present disclosure also discusses methods of making the instrument, desorption chambers, and methods for desorbing a component of interest from the instrument.

  • Patent number: 9625426
    Abstract: The invention describes the process by which a standard mixture of organic compounds are spiked and retained onto a composite sorbent matrix for the controlled generation of a standard in fluid above the spiked matrix either in a gaseous or aqueous phase. The novelty of the aforementioned composite matrix stems from the combination of an immobilizing liquid phase such as silicone oil or a polyacrylonitrile solution, and solid, porous particles such as polystyrene-co-divinylbenzene (PS-DVB) or hydrophilic/Lipophilic Balance (HLB) particles to strongly retain the spiked standards. These novel composite mixtures exhibit sorptive capabilities greater than the sum of their individual components. In addition swelling of the particles with the liquid phase facilitates immobilization of the composite sorbent matrix in the vial.

  • Publication number: 20160258910
    Abstract: The invention describes the process by which a standard mixture of organic compounds are spiked and retained onto a composite sorbent matrix for the controlled generation of a standard in fluid above the spiked matrix either in gas (headspace) or aqueous phase which is contained in portable vials. The novelty of the aforementioned composite matrix stems from the combination of an immobilizing liquid phase such as silicone oil or a polyacrylonitrile solution, and solid, porous particles such as polystyrene-co-divinylbenzene (PS-DVB) or Hydrophilic/Lipophilic Balance (HLB) particles to strongly retain the spiked standards facilitating high capacity which translates into prolonged use as a source of calibrant. These novel composite mixtures exhibit sorptive capabilities greater than the sum of their individual components producing a standard analyte generator far superior to those described in the prior art.
