Heated Static Headspace Injector	#SRI-8690-0045	$5,995.00
The Heated Static Headspace Injector is useful for the analysis of volatiles, especially where the sample matrix is dirty. 10-20 ml of sample is placed into a standard 40 ml VOA vial, which is inserted into a thermostatted sleeve. As the vial is inserted, two needles puncture the septum top of the vial. Purge gas enters through one needle to pressurize the vial, and the other needle carries the 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. The thermostatted sleeve is provided with a second VOA vial slot so that the next sample can be pre-heating and equilibrating while the current sample is being analyzed. The VOA vial sleeve can be thermostatted from ambient to 100ºC under control of the data system, so the vial can be cooled down prior to removal.
