iCAP 7000 Series ICP-OES Spectrometer
Data should be close to, or higher than those in the table below, to enable achievement of
acceptable detection limits.
If counts are not above those in the table then detection limits should be used for the pass fail
criteria.
Some elements in the High Concentration Standard Solution are not measured in the performance
testing of the instrument.
If the sensitivity test fails for Zn then the 'Service Installation Test' LabBook could have the
incorrect orders selected for the instrument being tested. Select the alternative orders by first
creating a new LabBook from the 'Service Installation Test' LabBook.
10.5.2.1
Change the Wavelength Order
To do this for a Zn line where the
sensitivity is low
Right Hand click on Zn then select edit
line library
Deselect the old order "Available for
Analysis" and "Use as Default"
Select the other order for the same
wavelength "Available for Analysis" and
"Use as Default"
Repeat Autopeak to ensure the lines are optically aligned.
10.5.2.2
Additional checks if the sensitivity is low
Note:- Boost purge is not used for testing the iCAP 7000 so Al and P have limits set for normal
purge. The detection limits and counts for all elements are specified for normal purge.
For Al ensure that the purge is OK
Check that the plasma image is positioned correctly on the slit
Check the nebuliser pressure is optimised.
