Abstract:
A portable high speed sampling and gas chromatographic separation system which is capable of sampling and analyzing molecules of interest, the system comprising:an input device for collecting sample particles having the molecules of interest at a first position; a port device capable of being heated by a heat pulse, the port device connected to the input device to receive sample particles having the molecules of interest at a second position, the molecules of interest releasing a vapor in response to the heat pulse applied to the port device; a gas column device connected to the port device, the gas column device receiving the vapor, the gas column device having a temperature lower than the port device, wherein the vapor is condensed in the gas column device, the gas column device further capable of being heated by a heat pulse, wherein in response to the heat pulse applied to the gas column, the condensed vapor of the molecules of interest separate into individual components and exit the gas column at different times; and a detector connected to the gas column device, the detector receiving the individual components of the condensed vapor, the detector for analyzing the molecules of interest.
