cumulative drift. (Figure 39)
Laser adjustment may be needed for the following reasons:
The laser's wavelength has drifted beyond the target range of the analyzer.
•
The analyzer is operated outside the recommended temperature range.
•
Figure 39 shows the offset between absorption peaks and target lines.
