Click OK and switch to the Analysis window.

Ensure the diluent tubing is connected to the Mariotte vessel and
the standard pump tubing is in the bulk standard, then press
Start .
NOTE
Follow steps 11–12 only if the Sampling Mode selected for the method is
manual (i.e. there are no prompt messages for an Autonormal method).
11
At the prompt, place the sample pump tubing in the same bulk
standard being supplied to the second pump and press
Read
(this calibrates the two pumps against each other).
12
At the prompt for Sample 1, remove the sample pump tubing
from the bulk standard, place it in the first sample and press
Read .
The top addition standard will be checked first to see if it is within
the linear reading range at maximum pump speed. If the absorbance
of the highest addition standard is greater than the LRR, the sample
will be diluted so that the absorbance is less than the LRR. All
addition standards will be determined using the same dilution factor.
A standard addition calibration will then be performed online.
NOTE
Any subsequent samples analyzed against that calibration (with a recalibration
rate greater than one) will be run at maximum pump speed to minimize loss of
sensitivity.
SIPS 10
Standard additions with the single pump system of the SIPS 10 is
effectively the same as in a non-pump system, however with the
added possibility of online dilution. This means that standard
additions solutions will still need to be pre-mixed.
