Description:
The design and fabrication of a completely portable, self-contained gas chromatograph is described. This instrument utilizes a closed-loop hydrogen carrier gas flow as maintained by a hydrogen generator-separator. It employs an auxiliary hydrogen generator to keep a positive flow of hydrogen through the detector. The detector is an ionization cross section detector. The only maintenance required is the addition of water (5-15 cc/day) to the auxiliary hydrogen generator. Lower limit of detection for the present system is of the order of 1-10 ppm ethane.
