WAIT
The AS waits for a continue command before proceeding with
the method. The command can be from the front panel (pressing
Hold/Run) or a TTL input. Each method must have one wait
step and no more. Sample prep operations can be added before
and after the wait step. By default, the wait step is at the end of
the sample prep phase.
The wait step can be disabled from the
SYSTEM PARAMETERS
screen (see Section C.6.5
).
REAGENT FLUSH
(concentrate mode
only)
Moves the specified volume of reagent from a reservoir or vial
to the inject port. This operation is used to flush reagent onto a
concentrator column.
μ
L: Reagent volume: The volume range and default
depends on the source, the syringe size, and vial size.
See “
Notes on Reagent Volume Ranges” on page 241.
source: Reagent source (enter either the vial from which to pick
up the volume of reagent or select the flush reservoir
(
FLH). If the sample prep option is installed, a reagent
reservoir can be selected:
RES A, RES B, RES C, or
RES D (default=FLH).
valve: Load/inject valve position:
L (load), (inject), or N (no
change) (default=
N).
REAGENT PRIME
(concentrate mode
only)
Moves the specified volume of reagent (100 to 50,000 μL) from
a reservoir to the waste port. This operation is used to prime the
sampling needle assembly with reagent when the AS is in
concentrate mode.
μ
L: Enter the reagent volume. The volume range and
default depends on the source, the syringe size, and the
vial size. See the notes under
REAGENT FLUSH.
source: Enter either the vial from which to pick up the volume
of reagent or select the flush reservoir (
FLH). If the
sample prep option is installed, a reagent reservoir can
be selected:
RES A, RES B, RES C, or RES D
(default=
FLH).
valve: Select the position of the load/inject valve:
L (load),
I (inject), or N (no change) (default=N).
