Traps are often the weakest part of the system. They should
be labeled, either on the trap itself or in accompanying
literature, with a maximum operating pressure. Source
pressure must not exceed the lowest maximum operating
pressure in the supply system.
Table 6 suggests starting values of source pressure.
Table 6 Suggested starting pressures
Gas Use Source pressure
Carrier Capillary columns 550 kPa (80 psi)
Air for FID, FPD Detectors 550 kPa (80 psi)
Hydrogen Detectors 410 kPa (60 psi)
Makeup gas Detectors 410 kPa (60 psi)
TCD Reference TCD 410 kPa (60 psi)
Air for valve actuators Valves 345 kPa (50 psi)
