SPECIAL CONSIDERATIONS FOR HYDROCARBON
FREE OPERATION
A special “hydrocarbon free” version of GPC1 (P/N 401801 or P/N 402201) is available. This part number is
delivered free of known sources of hydrocarbon in the GPC1 high pressure gas circuit. Of course, GPC1 will
remain hydrocarbon free only so long as hydrocarbons are not introduced from an external source.
To maintain a hydrocarbon free GPC1, only connect devices to it that are known to be hydrocarbon free.
If using a gas booster to supply the high pressure, the gas booster must be a hydrocarbon free version.
If using a PG7202 piston gauge, the PG7202 must be a hydrocarbon free version and used with Krytox
®
lubricated piston-cylinder modules.
