(2) Measurement of Raman Spectrum of Water
Set the flow cell unit in place, measure the Raman
spectrum of water under the conditions given below, and
record the results (see sections 3.4.2, 3.4.3, 3.4.5,3.4.6 and
3.5.2). Measure in the following sequence.
• Excitation (Ex) wavelength : 350 nm
• Time constant (response) : 2 seconds
• Photomultiplier voltage
• Emission spectrum
bandwidth
• Emission spectrum
measuring wavelength
• Spectrum No.
(a) Turn ON the power switch and the 1
appears.
(b) Set an excitation wavelength.
(i) Press the
screen appears. Set an excitation (Ex) wavelength.
