Injection; System Specifications - Teledyne Tekmar Versa User Manual

Therefore, the three variables, temperature, pressure and volume, have a direct affect on the sensitivity of the system.
The temperature in the Versa that would affect injection mass is the Valve Oven Temperature. The lower the temperature
used, the denser the mass of the gas in the loop. The pressure affects the sensitivity in two areas: the higher the vial
pressurization setting, the more dilution gas is added thus lowering sensitivity; while a higher loop fill pressure results in
higher sensitivity. The volume of the loop can be changed to allow for more mass to be injected on column. The volume
can be varied between the optional loop sizes of 100μl up to 5mL. The Versa is shipped with a 1mL loop.
Note: Refer to the Method Development section of this manual for further information on the effects of temperature,
pressure and volume.

Injection

Once the Sample Loop has been filled, and the GC is ready for injection and the 6-port valve is rotated. When the 6-port
valve is in the "B" position, it allows carrier gas to back flush the sample from the loop onto the analytical column. The GC
data system is started concurrently. The vial is lowered from the Platen and the sample pathway is subsequently swept
while waiting on the equilibration of the next sample to eliminate cross contamination.
