4 Controlling the Sampler
For a 6890A or 6890 Plus GC, the wash mode is controlled by entering a value
of:
• 1 for using solvent bottle A if injector uses solvent A washes and solvent
bottle B if injector uses solvent B washes.
• 2 for using 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.
• 3 for using 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.
The G2913A injector always uses both WA waste bottles if a solvent A wash is
used and both WB waste bottles if a solvent B wash is used.
Waste bottle mode—G2613 This is only displayed when the G2613A
injector has a 3-vial turret installed. On a 6890N GC the turret waste bottle
positions are controlled using the [Mode/Type] key:
• Use both A and B alternates between the two waste bottles
• Use only A bottle uses waste bottle A only
• Use only B bottle uses waste bottle B only
For a 6890A or 6890 Plus GC these turret waste bottle positions are controlled
by entering a value of:
• 0 for the A position only
• 1 for the B position only
• 2 to alternate between the two waste bottles
Solvent Saving—Use this option to vary the syringe wash amount from
about 20% to 80% of syringe volume. This setting reduces the amount of solvent
and sample consumed during each injection cycle. See “Sample Carryover" on
page 79 for more information.
On a 6890N, the wash amount is selected using the [Mode/Type] key. This
brings up a selection of actual wash volumes based on the volume of the
syringe used.
