    摘要： A system for interfacing a sampling device and a chromatograph and for pre-concentrating analytes in a sample prior to introducing the sample into the chromatographic column is generally disclosed comprising an interface housing with a first channel and an adsorbent housing with a second channel, which contains at least one adsorbent. Valveless conduits permit fluid to be communicated between the sampling device and the first channel, between the first channel and the second channel, and the first channel and the column. In some embodiments, fluid flows in one direction when the analytes are adsorbed and in the opposite direction when analytes are desorbed. In certain embodiments, two different adsorbents are disposed in the second channel to adsorb different types of analytes.

    摘要： The invention includes a method and apparatus for a chromatography system having a chromatographic column for separating gases in a mixture from one another and an electrochemical gas sensor coupled to the chromatographic column for detecting a gas being emitted from the column. The electrochemical gas sensor further includes a substrate having a surface for depositing electrodes thereon, an ionomer membrane in contact with the surface, an electrode in contact with the surface, and an opening in the ionomer membrane in a location proximate to the electrode for permitting a gas to diffuse through the opening to simultaneously contact the electrode and the ionomer membrane within the opening.

    摘要： Certain aspects and examples are directed to sorbent devices and methods of using them. In certain embodiments, a sorbent device comprising a body comprising a sampling inlet, a base and a longitudinal diffusion path between the inlet and the base is provided. In some embodiments, the sorbent device can include at least two sorbent materials fluidically coupled to the longitudinal diffusion path, in which the sorbent materials are arranged from a material with a weakest sorbent strength to a material with a strongest sorbent strength with the weakest sorbent strength material adjacent to the sampling inlet.
