摘要： A gas chromatograph is provided which is capable of effectively reducing the amount consumed of a carrier gas, reducing the time and effort required for an operator to manually set parameters, and preventing damages to a column and a detector due to a setting mistake. In a case where a stop operation for the power supply of the gas chromatograph is performed (Yes in step S101), the flow rate of a carrier gas to be supplied to a sample vaporization chamber is decreased and the temperatures of the column and the detector are sufficiently lowered (steps S102 to S104), and then the power supply of the gas chromatograph is switched over from an ON state to an OFF state (step S106).

摘要： An apparatus for detecting a presence of at least one analyte in a gas sample. The apparatus comprises a pump for drawing a gas sample from an ambient air, a passage having first and second ends, a chamber connected to the first end and containing a concentrating element for collecting at least one analyte from the gas sample, a chromatographic separator connected to a second end of the passage, and a gas source for streaming a carrier gas via the chamber to transfer the at least one analyte toward at least one chemical detector, via the chromatographic separator, in a first direction. The pump draws the gas sample via the chamber in a second direction and the first and second directions are substantially opposing to one another.

摘要： A fractional-volatilization separator includes a liquid inlet port for receiving a liquid mixture and a liquid waste outlet port for draining the liquid mixture. The fractional-volatilization separator includes a separator body having an interior wall portion connecting the liquid inlet port and the liquid waste outlet port. The fractional-volatilization separator includes a carrier gas inlet port coupled with the separator body for receiving a carrier gas, and a carrier gas outlet port coupled with the separator body for expelling the carrier gas. The interior wall portion is configured to cause the liquid mixture to flow from the liquid inlet port across the interior wall portion to the liquid waste outlet port to enhance evaporation of a first component part from a second component part of the liquid mixture as the carrier gas flows from the carrier gas inlet port to the carrier gas outlet port.

摘要： Apparatus, systems and methods are described for preconcentrators, chemical sensing systems and gas chromatographs. A preconcentrator is described that comprises a hollow enclosure containing a sorbent material. The enclosure may be a capillary tube that can be formed in to a desired shape and that may be heated. Heating may be accomplished by passing an electrical current through the capillary or other hollow enclosure form. The sorbent material can be a liquid, a solid, a porous ceramic material and/or a chemiselective polymer. The sorbent material can be coated to the inner wall of the enclosure. The hollow enclosure may be maintained in an insulated chamber. The preconcentrator acts to concentrate a vapor passed through the preconcentrator to a chemical sensing array that can detect chemicals present in the vapor. A gas passed through the hollow enclosure can provide a chemically concentrated input to a chromatographic column.
