Tubing
For the hydrogen supply line, it is recommended that only clean grade copper or
stainless steel tubing should be used.
Plastic tubing material such as Teflon®, polyvinyl chloride, or Tygon® should not be used
when plumbing GCs since these materials will allow air and water to diffuse into the gas
lines. In addition, plastic tubing can give off organic impurities which can cause ghost
peaks and baseline instability.
Furthermore, Peak Scientific recommend that compression fittings are used, and that
the fittings are free from Teflon® tape.

Ventilation
Peak Scientific recommends that both the H

Exhaust and H

Vent ports at the rear of
the unit should be connected to an exhaust hood, or other ventilation system, to ensure
safe disposal of vented gasses. Tubing sizes for the vent ports are 4mm OD for the H
2
Exhaust and 6mm OD for the H

Vent.
