Sample Preparation Option Functions
The
AS
can be equipped with a sample preparation option that includes a
sample prep syringe, a sample prep valve, and one 250 mL reagent
reservoir. Up to three additional reagent reservoirs can be configured.
The sample prep syringe performs these operations:
•
Dispenses reagents from external reservoirs to any vial
•
Mixes a vial by repeatedly drawing and expelling the vial contents
•
Performs dilutions, allowing preparation of multilevel calibration
standards
•
Performs liquid-liquid extractions by adjusting the height of the
needle in the vial
The following sample prep syringe volumes are available:
The reagent reservoir connects to port A on the sample prep valve.
Additional reservoirs can be connected to ports B, C, and D. Commands
from the AS front panel screens or from Chromeleon or Chromeleon
Xpress let you select the reservoirs.
NOTE The 5 mL and 10 mL syringes are intended for most
sample prep functions. Use the smaller syringes only
for applications that require low flow rates.
NOTE The 2.5 mL syringe (P/N 055067) can only be used
with the sample preparation option. It cannot be
used as a sample syringe.
