Operator’s Manual for the Pressure Injection Cell
BE SAFE. ALWAYS MAKE SURE THAT THERE IS NO PRESSURE IN THE CELL BEFORE
LOOSENING THE BOLTS, AND THAT THE BOLTS ARE SECURELY FASTENED BEFORE
APPLYING PRESSURE TO THE CELL. USERS MUST ALWAYS WEAR PROTECTIVE
APPAREL, INCLUDING EYEWEAR AND MUST BE TRAINED IN WORKING WITH HIGH
PRESSURE.
ferrule, place a new ferrule, tapered side
down into the fitting, and replace the
nut. Your pressure injection cell comes
with 10 ferrules (plus one installed in
the top). Additional ferrules can be
purchased directly from
Chromatography Research
Supplies (part number 214204, 1/8” to
0.4mm PTFE ferrules), at

DISCONNECTING AND
RECONNECTING THE UNIT
Before you disconnect the pressure
injection cell, mark lines on the nut and
the valve, close the valves by the
pressure source, and release any
pressure inside the cell by opening the
3-way valve. When you reconnect the
unit, you can use the same ferrule and
tubing. Simply tighten the nut slightly
more than last time. You should feel the
wrench get very hard to turn once you
go beyond the nut’s previous position.
TROUBLESHOOTING

injection-cell-troubleshooting.
If gas leaks through the top-base
interface of the pressure injection
cell, the three bolts might not be fully
tightened or the O-ring might be nicked
or dirty or missing. If the O-ring is
dirty, wash it off with a soap and water
and return it to its groove. Contact us
for a replacement O-ring.
If gas leaks around the capillary,
the ferrule should be replaced.
If you do not see sample traveling
through the capillary after a few
minutes, check that the gas tank is
supplying the
desired pressure
(typically on the order of several
hundred psi) and that the 3-way valve
knob is pointing toward the pressurized
gas line.
