Lets syringe interface with gas cylinder
The Pressure-Flo high pressure syringe is a tried and truemethod of taking
homogeneous high pressure samples froma cylinder or“bomb”. It contains
the sample in a calibrated needle with a wire plunger to displace it and PTFE
packing to seal it in, permitting injection of the sample directly through the
GC septum inlet for convenience and simplicity.
The body of the syringe is lightweight for easy handling. It houses a special
crimped PTFE packing which seals firmly at pressures up to 500 psi even
under severe operating conditions. Threads allow the syringe tomake up on
a cylinder via the special adapters listed below. Once the syringe is screwed
tight, the cylinder valve is opened and the plunger is depressed, extending the
needle into the liquid zone. Once sample is drawn into the syringe, it is stored
pressure-tight while the cylinder valve is closed and the syringe is removed
from the adapter.
To inject the sample, the nose of the syringe is pressed very firmly against the
septum to form a pressure-tight seal. (This requires a minimum1/8" hole in
the septum cap.) As this is done, the pointed tip of the needle punctures the
septum. When the large handle is pushed in, the needle containing the
sample is inserted into the injection port without any loss of contents.
