Standard Additions Calibration
SIPS 20
The dual pump system of the SIPS 20 performs standard additions
calibration using one pump to deliver sample at a constant rate,
while the other delivers standard solution over a range of rates.
To use automatic standard addition calibration with a SIPS 20:
1
Develop or modify a method according to your analytical
requirements (refer to the online help for details).
2
To incorporate SIPS operation in the method, enable the
Use
SIPS
checkbox on the
Type/Mode
page of the
Method
window.
3
On the
Measurement
page:
a
Enter a value for the
Read Delay
. This represents the time
required to pump solutions introduced with SIPS through the
pump tubing to the T-piece.
b
Select
Standard Additions
as the calibration mode.
4
On the
SIPS
page:
a
Select
Bulk Standard
from the
Right Pump
group. If you will
be running a very long autorun, with many samples, it may
be necessary to periodically recalibrate the pumps during the
run. Select the appropriate option from the
Dual Pump
Recalibration
group.
b
Select the
Calculate LRR
during autorun
checkbox if you
want to determine the LRR (Linear Reading Range) during
the run. Otherwise leave this box unchecked and the value in
the entry field will be used as the LRR for that method.
5
On the
Standards
page, set the
Bulk standard concentration
and
the
Standard count
.
6
Fill in the remaining pages in the
Method
window as desired and
click
OK
.
7
Insert the method into a sequence, developing the sequence
according to your requirements (as described in the online help).
