Abstract
A gas chromatograph having a gas inlet port, a sealed fluid flow channel, a gas outlet port, a gas outlet port in fluid connection with a second end of the fluid flow channel, and a gas molecule detector in fluid connection with the gas outlet port, is disclosed. The first end of the sealed fluid flow channel is in fluid connection with the gas inlet port. The sealed fluid flow channel contains one or more pairs of electrodes running lengthwise along the inner surface of the fluid flow channel.

A method of separating gas molecules in a sample, the method comprising:
- providing a sample containing sample gas molecules;
- contacting at least a portion of the sample and a carrier gas to form a sample/carrier gas mixture;
- introducing the sample/carrier gas mixture into a fluid flow channel containing an inlet and an outlet, wherein the fluid flow channel contains at least one pair of electrodes running lengthwise along the inner surface of the fluid flow channel;
- applying an alternating current to the electrodes running lengthwise along the inner surface of the fluid flow channel;
- flowing the sample/carrier gas mixture from the fluid flow channel inlet to the fluid flow channel outlet while the alternating current is applied to the electrodes;
- and
- detecting the presence of sample gas molecules exiting the fluid flow channel outlet.
