The 6850 automatic liquid sampler
The sample turret
The sample turret contains positions for 27 2-mL vials. The optional 4-mL
sample vial turret has a capacity of 22 vials. See Figure 47. When used with
Agilent Cerity Chemical or ChemStation control software, the sample vials can
be analyzed in random order. If controlled using a G2629A Control Module, you
must load your sample vials in the order you want them run.

Solvent and waste bottle usage
When a syringe is washed (both pre- and post-injection washes), it is filled to
80% of its full volume and then emptied into a waste bottle. Sufficient solvent
must be available for the washes and waste bottles must be present to receive
the used solvent.
