Configuring the injector on a 6890 GC
Press [Config] [Front Injector] or [Config] [Back Injector] to display the parameters.
Scroll to the desired parameter detailed below.
Tower position—Injector cables are connected to either the INJ1 or INJ2 port
on the GC. This setpoint indicates which tower is on which inlet. You do not have
to move cables when you switch the towers, merely reconfigure the tower
position. Use the [Off] button to toggle this location.
Syringe size—6890N only. Enter a syringe size between 1 and 100 µL.
Wash mode—G2913 This is only displayed when the G2913A injector has a 1-vial
turret installed. On a 6890N GC the turret solvent bottle positions are selected
using the [Mode/Type] key:
Wash using A, B—Uses solvent bottle A if injector uses solvent A washes
and solvent bottle B if injector uses solvent B washes.
Use A-A2, B-B2—Uses solvent bottles A and A2 if injector uses solvent A
washes and solvent bottles B and B2 if injector uses solvent B washes. The
injector alternates between both bottles.
Use A-A3, B-B3—Uses solvent bottles A, A2, and A3 if injector uses solvent
A washes and solvent bottles B, B2, and B3 if injector uses solvent B washes.
The injector alternates between all bottles.
