The Heated Static Headspace injector is useful for the analysis of volatiles, especially where the sample matrix
is dirty. A
and fixed volume sample loop are used for maximum precision.
The thermostatted headspace sleeve accepts standard 40 mL VOA vials containing 10 - 20 mL of sample.
Solenoid valve
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
A solenoid valve located at the loop exit is opened under
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 headpsace sleeve is thermostatted from ambient to 90 ° C under PeakSimple control, and can be
cooled down before removing the VOA vial.
