Warning: Use caution when working with hydrogen. Hydrogen mixed with air can be both flammable and an explosion hazard.
Turn off the hydrogen supply at its source before working on the instrument.
Note: Use new, clean tubing for the installation of the gas line. Hydrogen can remove deposits on the inside of old tubing, and this may
affect the operation of the methanizer.
Note: Use stainless-steel tubing for the hydrogen gas line. Copper can become brittle when exposed to hydrogen gas, which could create
a safety hazard.
Note: Use hydrogen that is of carrier gas purity (99.999% or greater) and use gas filters to remove hydrocarbons, water, and oxygen.
Figure 2 shows the ideal use of parts to plumb the hydrogen source line to the hydrogen supply line of the methanizer. If the operator chooses
to run a dedicated gas supply line from a gas bottle or generator for the methanizer, then the tee is not needed. If the operator chooses to
splice into the existing gas line supplying hydrogen to the FID, the following procedure should be used.
4.1 Verify hydrogen is switched off at its source.
4.2 Locate the hydrogen source supply line at the back of the GC and install a
4.3 Install the ball valve after the tee using a short length of
4.4 Install the MINICYL regulator after the ball valve using a short length of 1/8" stainless-steel tubing.
4.5 Install the metering gas valve using a short length of 1/8" stainless-steel tubing.
4.6 Install the 1/8" to 1/16" tube end reducer into the output end of the metering gas valve.
NOTE: A hydrogen supply line (cat.# 27208) is included with the methanizer. It will be connected to the tube end reducer in the installation
section of this manual.
