Figure 3–21: Scan of anthracene at 100 nm/min and 1000 nm/min
Tip:
The higher the number you enter in the Pace field, the lower the resolution
of the scan.
• Tick marks – This value allows tick marks (check marks) to be generated at the
specified wavelength increment help interpret charted data.
The figures below show a 190-nm to 600-nm scan of erbium standard in a
cuvette at 200 nm/min, with tick marks specified every 20 nm, and the same
scan without tick marks.
• AUFS – The sensitivity setting used for scaling the charted spectrum.
