IV. SAFETY PRECAUTIONS
WARNING
1. The maximum concentration of Oxygen allowed in the gas is 0.5%
2. The maximum system pressure is 150 psig (10Bar)
3. Do not install a PUR-Gas purifier system near or in an excessively hot area
(i.e., the hot-air exhaust at the rear of the GC)
4. Install purifier cartridges in the appropriate position as indicated on the
top of the baseplate
5. Perform a reliable leak test when installing a baseplate or purifier
cartridge
6. Handle the purifier cartridge at the top of the housing and keep the
cartridge upright when installing to avoid torsion/damage to the plastic
exterior cover on the purifier cartridge; check for any cracks on the inner
glass tube after installation
7. NEVER REMOVE the white plastic mounting plugs located on the outside
housing near the bottom of the cartridge; if they are missing, the cartridge
should NOT be installed and should be returned to MATHESON
8. NEVER replace the baseplate fittings; if new fittings are required, contact
MATHESON for technical assistance.
9. Use only original MATHESON baseplates; all warranties are voided with
the use of a different model baseplate or other device.
V. GENERAL DESCRIPTION
MATHESON PUR-Gas purifier cartridges are designed for the purification of non-
corrosive gases with low concentrations of contaminants to better than 6.0 grade
(99.99990 %) purity.
MATHESON PUR-Gas purifier cartridges are connected to an appropriate baseplate
which is installed into the gas line.

VI. INSTALLATION OF A BASEPLATE
NEVER INSTALL AN OXYGEN PURIFIER IN A BASEPLATE POSITION
SUITED FOR AIR. It will result in instant saturation!
A baseplate assembly can have either 1, 2, or 3 positions, depending on the number of
gas purification applications. The following instructions are valid for each individual
position on the baseplate.
1. Shut off the incoming gas source.
2. Cut the gas line using an appropriate metal tubing cutter.
3. Connect the gas Inlet (1) and Outlet (2) as indicated at the rear of the baseplate,
keeping the connections loose.
4. Turn on the gas source and flush the line for at least 10 minutes with pure
carrier gas at 8 psig minimum.
5. Tighten the incoming gas line at the Inlet (1) rear fitting.
6. Ensure that the flushcap (4) is securely tightened to the baseplate; push the cap
down during mounting procedures.
7. Attach the baseplate using mounting holes (3) or use an optional wall mounting
bracket.
8. Turn on the gas source and flush the line for at least 10 minutes with pure
carrier gas at 8 psig minimum.

6
9. Remove the flushcap (4) by turning the knurled ring (5) counter-clockwise until
the flushcap can be removed.
a. Note: As long as a purifier cartridge is not installed, no gas will
pass through the baseplate.
10. Install a new purifier cartridge on the baseplate. See SECTION VIII,
Installing a Purifier Cartridge, for more detail.
11. Flush the whole system for 15 minutes with pure carrier gas, at a recommended
pressure of 90 psig.
12. Tighten the outgoing gas line at the Outlet (2) rear fitting.
The analytical system is now ready to be used. Argon or Nitrogen peaks in the
chromatogram should be negligible.
➢NOTE: Always check for possible leaks in the system before operation.

VII. STANDARD PURIFIER CARTRIDGE/BASEPLATE COMBINATION
1. Purification System for GC/FID
High Capacity: Triple + 2x Combi purifier on 3-position baseplate
2. Purification System for Fuel Gas/FID
2x Combi purifier on 2-position baseplate
3. Purification System for Carrier Gas with MS-ECD-NPD
Triple purifier on 1-position baseplate

8
VIII. INSTALLING A PURIFIER CARTRIDGE
1. Remove the two metal diffusion-proof plugs from the purifier cartridge Inlet
and Outlet (positioned at the bottom of the cartridge).
2. Remove the knurled ring (5) from the baseplate and place it around the purifier
cartridge.
3. Place the purifier cartridge, along with the knurled ring, onto the baseplate,
making sure all three holes on the bottom of the cartridge align with the two
valves and positioning pin located on the baseplate.
4. Push the cartridge completely down onto the baseplate, and hand tighten the
knurled ring while holding down the cartridge until it is firmly connected to the
baseplate.
NOTE :
1. Once the purifier cartridge is positioned on the baseplate the Teflon seals will
be punctured. It is necessary to keep the purifier cartridge in position to prevent
air from entering the system.
2. Regularly check both the big and small Viton O-rings on the baseplate for hair
cracks. The slightest leak allows moisture, oxygen and hydrocarbons to enter
the system and contaminate the gas.
3. All MATHESON PUR-Gas purifier cartridges are packed under Argon, except
for the special Helium-specific GC/MS purifier cartridges.
IX. REPLACEMENT OF A PURIFIER CARTRIDGE
A purifier cartridge needs to be exchanged when the visual indicators start changing
color. The original indicator color and the color after saturation are listed in the table
