The second function of the Calibration page (Figure 5.13) allows the
operator to determine wavelength accuracy and correct any errors if
necessary.
Figure 5.13 The Calibration Page
The alignment of the spectrum on the diode array is dependent upon
the physical alignment of various components of the optical bench
and can become off set if the detector is sharply jolted, for example,
in shipping.
PERFORMING A
WAVELENGTH
CALIBRATION
To perform a wavelength calibration, proceed as follows:
1. Turn on both lamps and wait 1 hour for the deuterium (D
2
)
lamp to warm up.
2. Pump water at 1 mL/minute through the flowcell.
3. Place the filter wheel in position 1, Open.
4. Click the Open button in the Wavelength File group.
