Heated Static Headspace Injector
The thermostatted headspace sleeve accepts standard 40 mL VOA vials containing 10 - 20 mL of sample.
Heated Static Headspace Injector as the vial is inserted into the headspace sleeve, two needles puncture the septum top of the vial. Purge gas enters through one needle to pressurize the vial, and the other needle carries headspace vapors to the loop of the gas sampling valve. A solenoid valve located at the loop exit is opened under PeakSimple data system control to allow headspace vapors to purge through the loop just prior to injecting the loop contents onto the column. The entire headspace sleeve is mechanically agitated under control of the data system.
