4 Troubleshooting and Test Functions
Check of Raman Band of Water
This test is a verification of the wavelength calibration, described in section
“Wavelength Verification and Calibration" on page 101, using the Raman band
of water.
Using the Agilent ChemStation
1 Copy the method WLEMTEST.M and WLEXTEST.M to \HPCHEM\1\
METHODS.
2 Load the method WLEXTEST.M. The FLD will change into the
multi-emission mode and scan in the range of the expected maximum of
397 nm
±20 nm.
3 Turn the pump on and flush with water for a few minutes to assure a clean
flow cell. Flow rate should be 0.5 to 1 ml/min and the baseline stable.
4 Define in Sample Information the file name and description.
5 Start a run. After the 1 minute run has completed, enter the Data Analysis
and evaluate the spectrum. The maximum should be found at
397 nm
±3nm, see Figure 34 on page 105.
NOTE
This test requires the Agilent ChemStation Spectra module or the Control Module.
NOTE
The methods WLEMTEST.M and WLEXTEST.M are part of the A.06.xx ChemStation
software CD (\1100FLD\VERIFYWL\).
NOTE
You may remove the flow cell and check for air bubbles. After re-inserting the cell, turn the
lamp on.
