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.
SETTING UP YOUR
PRESSURE INJECTION CELL
Setting up the Pressure Injection
Cell consists of attaching it to 1/8 inch
(outside diameter) thick walled stainless
steel tubing (not supplied with the
PC1000 Pressure Injection Cell). First,
slide the tubing through the inlet nut
until it hits a stop. Finger-tighten the
nut and then tighten it with a wrench for
1-1/4 turns. Connect the other end of
the tubing to a pressurized gas tank. It
is now set up.
USING YOUR PRESSURE
INJECTION CELL
OVERVIEW
Using the pressure injection cell
requires removing the top, inserting
your sample, replacing the top, and then
inserting a capillary. Next, inject the
sample using pressurized gas to force
the sample through the capillary. After
the injection, close the gas tank valve
and open the 3-way valve to release the
pressure.
REMOVING THE TOP
With the valves at the pressure
source turned off and the 3-way valve
opened to release any pressure inside
the cell, loosen the three bolts securing
the top, 2 turns each. Rotate the top
counterclockwise by 60 degrees so that
the hexagonal sides are even. Then lift
off the top.
INSERTING THE SAMPLE
Place the sample tube in the main
hole of the base. The tube should not be
capped. If the cap is hinged, you must
cut off the hinge (with scissors). There
is a recess in the top so the tube can
protrude from the base, but a hinged
cap will not fit in the recess.
The sample tube protrudes from the base for
easy insertion and removal.
REPLACING THE TOP
Confirm that the black O-ring is
seated in its groove. Slip the top onto
the base, rotate the top 60 degrees
clockwise, and then tighten the three
bolts using a hex wrench.
