complete, the VIS coefficients and RMS (Root Means Square) value will be
displayed in the Wavelength/Calibration window. These values should meet the
following specifications.
VIS Coefficients and RMS
First Coefficient
Second Coefficient
Third Coefficient
RMS
(measures variability of
wavelength offsets)
If these specifications are not met, repeat the wavelength calibration and make sure
all peaks can be seen in the Spectra Display window. If these specifications are still
not met, a complete optical alignment may be required. Contact a PerkinElmer
Service Representative.
Setting Instrument Parameters
General Parameter Settings
Optimum conditions will depend on the type of analyses being performed. You use
the ICP software to set up the instrument parameters. The following settings are
general recommendations. For more information on the parameters, refer to the
Software Guide on the software CD. The following parameters are set in the
method:
•
A Max time of 50 seconds may be required for detection limit work.
•
•
We recommend you use Auto integration with the following settings:
Read Parameters
Time: Auto: Min: 2 sec, Max: 10 sec
Make sure that the read delay, wash time, and rinse times are sufficient.
Re-check the Interelement Corrections (IECs) if you make any changes to
the ionization or excitation characteristics of the plasma after collecting
IEC data. This would include changing the source conditions or changing
the nebulizer or the torch.
