Transfer only enough Sample Solution for use in half-hour
increments. The total volume of Sample Solution required depends
on the sample volume and the total number of data points being
generated. The volume graduations on the Transfer Pipette as well
as the 1 mL mark on the Sample Aliquot Container can be used as
a guide.
IMPORTANT When handling open Blank Reagent Vials and open Sample Solutions, be very
careful not to spill any liquid on or along the edges of the Instrument’s keypad.
When calibrating a pipette, there is an inevitable linkage between
operator technique and pipette performance. For meaningful
results, it is recommended that standard laboratory pipetting
technique be used and that specific pipette manufacturer's
instructions are followed. Using the PCS for training purposes
provides the opportunity to improve technique and to optimize
pipetting accuracy and precision. For additional technique
instructions, contact ARTEL Technical Support, and refer to the
information included in the back of the Procedure Guide.
4.7.3 Aspirate the Sample Solution from the Sample Aliquot Container
with the pipette to be calibrated, using standard pipetting technique.
Place the cap lightly back on the Sample Aliquot Container between
samplings to avoid reagent evaporation.
4.7.4 Lift the Instrument Vial Holder Cover and dispense the Sample
Solution into the Blank Reagent Vial.
IMPORTANT The Sample Solution should be dispensed against the inside wall of the vial with
the pipette tip placed above the meniscus but below the shoulder of the Blank
Vial. The vortex mixing action will wash the solution from the inside wall of the vial.
4.7.5 Once the sample is dispensed, carefully withdraw the pipette and
close the Vial Holder Cover.
The Instrument will then display:
