Syringeless Injector
Dramatically increase the capabilities of your Gas Chromatograph, by simply inserting the Syringeless Injector into your injection port. Syringeless injection eliminates the restrictions of Syringe injection. Analyze solids and viscous liquids without solvents or complicated sample preparation. The Syringeless injection technique can be used in a number of unique applications to solve difficult analytical problems. See Applications
The innovative design of the Syringeless Injector allows the sample to be positioned within the injection port, ~2cm above the inlet of the capillary column. This location provides uniform sample heating and reduces the path that volatiles have to travel to a minimum. Preheated carrier gas continuously sweeps any volatiles released from the sample into the capillary column for collection and separation.
See Tutorials.
