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:
Select Manganese, which is typically used as the alignment wavelength for the
majority of analyses.
-or-
Select another element from the drop-down list. This feature is for specialized
analyses where you want to optimize the intensity for an individual analyte of
interest. This may adversely affect the intensities of other analytes.
12. Set the Read Delay time.
13. Aspirate a solution containing the element you have selected.
When using radial viewing, the system adjusts the lateral viewing position
only.
When using axial viewing, the system adjusts both coordinates.
The system will determine the intensity at the selected wavelength, while
adjusting the viewing position in incremental steps. In the Results window, a
report is generated that gives the intensities found at each position. The system
changes the Torch Viewing Position to the position that gives the highest
intensity. In the Spectrometer Control window, the software resets the
coordinates so that the 0 and 15 position is at the location of highest intensity.
Detector Calibration
Detector calibration is the process of collecting and processing the detector signal
bias and dark current data needed to quantify signals from the detectors properly.
The plasma does not need to be on for this procedure.
To perform detector calibration:
1. In the Tools menu, click on Spectrometer Control.
The Spectrometer Control window appears.
