Setting the Torch Viewing Position

This procedure adjusts the torch viewing position for the highest signal intensity.
Perform this procedure when:
•

•
1. Switch on the computer and spectrometer, and if required, the autosampler.
2. Switch on the exhaust ventilation system.
3. Start the ICP software.
4. In the Instrument tab->Devices->Autosampler tab, and make sure that the
software is configured for the autosampler tray you are using.
5. In the Instrument tab-> Plasma Control and ignite the plasma. Allow the
torch to warm up for half an hour before you start the alignment.
6. Prepare a solution containing 1 ppm manganese.
7. In the Instrument tab-> Spectrometer Control.
The Spectrometer Control window appears.
8. Select Axial or Radial. We recommend that you first do the alignment in one
viewing mode, then select the other viewing mode and repeat the procedure.
9. To view spectra collected during the procedure, open the Spectra Display
window.
10. Click on Align View in the Spectrometer Control window to open the Align
View dialog or select Align View from the software ribbon.
11. Select the element and wavelength. This is the wavelength that the system will
use to measure the intensities at different viewing positions and locate the
position that gives the highest intensity. Your options are:
the instrument or software is first installed
the instrument is moved to a new location
the torch is removed or replaced
the plasma induction plates are replaced
