Item Description
Volatile Sample Used with samples in a high vapor pressure
solvent. A solvent flush sampling mode with
slow plunger speeds and no upper air gap to
minimize flashing of the sample during
sampling.
Neat Sample Used to minimize the solvent that is injected
with the sample. In this mode, solvent flush is
turned off. The syringe is washed several
times with the sample and overfilled with
sample. During injection only the specified
amount of sample is injected from the syringe
and the excess is expelled into the waste arm.
Viscous Sample Used with samples that have a higher
viscosity than water. A solvent flush sampling
mode with slow plunger speeds and longer
pauses to improve reproducibility with higher
viscosity samples.
User Defined Allows you to set the 8200 AutoSampler
parameters. When this mode is selected the
User Defined Parameters subwindow is
displayed with the parameters available for
editing.
SPME Mode When the SPME (Solid Phase
MicroExtraction) sampling mode is chosen,
the SPME Options subwindow is shown.
Liquid Sampling Options
Item Description
Wash Mode Choose from:
Solvent A Wash
Solvent B Wash
A then B Wash
No Wash
Selects the solvent used to wash the syringe
after sampling and to create the solvent plug
before sampling a vial. When the solvent A
then solvent B wash mode is selected, solvent
A will be used for the solvent plug.
Syringe Volume Either 10 microliters or 100 microliters.
Selects the size of the syringe that is installed
on the 8200 syringe.
