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 Swagelok® fittings are used, and
that the fittings are free from Teflon® tape.

Ventilation
Peak Scientific recommends that both the H
2
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 1/8” OD for the H
2
Exhaust and 3/8” OD for the H
2
Vent.
