is Syringeless Injection?
Syringeless injection is a powerful new injection technique for
Gas Chromatography that replaces the standard injection port liner.
Samples no longer need to be diluted with a solvent prior to analysis.
You can now analyze a broad range of materials directly within the
Samples to be analyzed are placed into a sample vial then loaded
into the Syringeless Injector. The Syringeless Injector moves the
sample vial into and out of the injection port by controlling the
split vent carrier gas flow. Efficient transfer of volatiles directly
into the capillary column is accomplished by inverting the sample
vial over the inlet of the capillary column. The Syringeless Injector
requires no septa or transfer line, allowing the injection port
to operate at maximum temperature without any interference from
septa bleed. Unlike syringe injections the Syringeless Injectors
ability to expel any unvaporized sample prevents the build up of
contaminants within the injection port.
The Syringeless Injector installs by simply replacing the injection
port liner. No permanent modifications to the injection port are
