Using the Active Method
3-62
This option instructs the autosampler to interrupt the vial injection sequence and inject a
"Priority" vial that has been placed in the "Priority" position of the turntable. The priority
vial will be injected after completion of the current run.
After the priority vial has been injected (in accordance with the current program
parameters), and the priority run completed, the program continues with the next
injection in sequence.
NOTE: Priority can only be selected when with the above screen is visible.
About Waste and Wash Vials
The Autosampler software has been optimized to use waste vials and solvent wash vials
to minimize contamination of the syringe needle.
Septa are available for the waste vials and solvent wash vials by ordering P/N N930-
2780. We recommend using these septa in place of the diffuser caps when you are using:
• Very viscous samples (to wipe the sample off the outside of the syringe needle).
• Toxic solvents and samples.
• Very volatile solvents.
Multi-Program Mode
Waste Vials
When operating in the Multi-Program Mode, the sample pre-washes are emptied into
waste vial #1 for program 1 and waste vial #3 for program 2. The solvent post-washes
are emptied into waste vial #2 for program 1 and #4 for program 2.
Wash vials
Program 1 splits between solvent wash vials #1 and #2. For example, if four washes are
required, two will be taken from vial #1, and two will be taken from vial #2.
Program 2 splits between solvent wash vials #3 and #4. For example, if five washes are
required, three will be taken from vial #3, and two will be taken from vial #4.
