Mini Injector
Reproducible sample injections down to 0.01 µl
Without a splitter
Sample carried in the plunger itself
The groove containing the sample is machined on the plunger,insuring
repeatable results
TheMini Injector is ideal for capillary GCwork, allowing reproducible injection
of small samples (down to 0.01 µl) without a splitter. This is possible through
our unique use of a plunger-within-a-needle. The sample volume is carried in
a preciselymeasurable groove ringing the wire plunger,with a durable PTFE
packing to prevent leakage.
In use, the plunger is extended beyond the needle tip and dipped into the
sample,where capillary action fills the groove. Then the plunger is drawn
through a PTFE wiper and back into the needle for protection. When the
needle is inserted into the inlet and the plunger is depressed, the sample
carried on the plunger groove enters the heated zone, where it is flash-
vaporized and swept into the column.
