3. Make sure that the torch is correctly installed, the torch compartment door is
shut, and the EMO switch is released.
4. Make sure the drain vessel is empty.
5. Switch on the spectrometer, and if required, the autosampler.
6. Switch on the chiller.
7. Switch on the computer and start the ICP software.
8. In the in the Instrument tab, click on Plasma Control and ignite the plasma.
Allow the torch to warm up for 30 minutes before you start making measurements.
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:
• We recommend you use Auto integration with the following settings:
Read Parameters
Time: Auto: Min: 0.5 sec, Max: 2 sec
A Max time of 50 seconds may be required for detection limit work.
•
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.
• To compensate for spectral interferences, use Background Correction,
Interelement Correction (IEC), or Multi-component Spectral Fitting (MSF).
Confirm using interference check standards.
• To compensate for matrix effects, use internal standardization.
