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.
Use a hex wrench to tighten the three bolts.
INSERTING A CAPILLARY
Loosen the nut covering the white
ferrule using a wrench. Slide the
capillary through the small hole in the
ferrule, until it reaches the bottom of
the sample tube. Tighten the nut,
thereby squeezing the ferrule tightly
around the capillary.
To remove the capillary, loosen the
nut and slide the capillary out.
INJECTING A SAMPLE
First point the knob on the 3-way
valve towards the stainless steel tubing
connected to the gas tank. Then, while
looking away from the gas tank gages
and with your hand covering them (in
case they explode when the pressure is
turned on) open the gas tank valve.
Adjust the pressure regulator to the
desired pressure.
When the injection is finished,
close the gas tank valve. Then turn the
knob on the 3-way valve so that it
points toward the vent.
This depressurizes the injection cell.
Now you can loosen the nut over the
ferrule and remove the capillary, loosen
the three bolts, remove the top, and
remove your sample tube
.
Use a wrench to tighten the nut, forcing the
ferrule to squeeze tightly around the capillary.
USE OF ADAPTER FOR 1 ML
TUBES
We supply one adapter with the
pressure injection cell so that 1 ml tubes
are as easy to work with as taller tubes.
