8.2 Operation
Operate the system at 400 °C. Once every week, turn the temperature up to
450 °C for one (1) hour. After one hour, reduce the temperature to 400 °C and
return to running samples. This procedure will eliminate any H
2
that may have
accumulated during that week.
9 Waste Disposal
This procedure is for GOW-MAC Mini Purifier Part No. 180-542 (Helium) and
180-542-AR (Argon).
If the purifier is used, then the getter material inside the purifier is already in a non-
reactive state, (i.e. will not react with air).
If the material is still in a reactive state (i.e. the purifier is not completely "used up"),
it still will not sustain combustion in air except at temperatures over 350 °C,
and with a continued access to air.
The operator should place a VCR cap over the inlet/outlet fittings for sufficient
precaution before disposal. It is then acceptable to deposit in an approved landfill,
in accordance with local, state and/or federal regulations. When disposed of in this
manner, the waste poses no known environmental problems.
