Cryofocused Sampling of Volatiles from Air Using Peltier-Assisted Capillary Microextraction

摘要

A CMV sampling device includes a thermoelectric cooler, a vacuum pump, and one or more holders for one or more capillary microextractor of volatiles (CMV) tubes. The holder thermally contacts the thermoelectric cooler and the vacuum pump is fluidly connected to the CMV tube. The CMV device is useful for sampling of volatile organic compounds from air. The sampling can be carried out rapidly to achieve a sample within the CMV tube that may be placed into a thermal desorption unit (TDU) coupled to an inlet port for introduction of the volatiles into an analytical instrument, such as, a gas chromatograph (GC), an ion mobility spectrometer (IMS), a liquid chromatograph (LC), and/or a mass spectrometer (MS) for analysis of one or more volatiles.
