Specifications

1. Optical system:
Ratio photometry;
intensity of transmitted beam is monitored.
2. Light source:
Xe lamp (150 W)
Hg lamp (for checking wavelength)
3. Measuring wavelength range Excitation wavelength:
200 to 850 nm/Zero order
4. Measuring wavelength range emission wavelength:
250 to 900 nm/Zero order
Photomultiplier must be changed at emission wavelength greater than 731 nm.
5. (Spectral bandwidth excitation side: 15 nm
6. (Spectral bandwidth emission side:
15 nm, 30 nm (variable)
* With this instrument, spectrum bandwidth is defined by half-value width. Therefore, in order to
separate a spectrum completely, a wavelength interval of 30 nm or more is required.

By communication (E-line) or keyboard
8. Wavelength accuracy: ±3 nm
9. Wavelength repeatability: ±0.5 nm
10. Recorder output (option):
10 mV full-scale;
full scale range 1 to 1000 settable in increments of 1
11. Processor output (option):
1 V full-scale
-40 to 1000 mV
12. Response :
Changeable in 7 steps corresponding to time constants of 0.05/0.1/0.5/1.0/2.0/4.0/8.0 seconds.

S/N ratio for Raman peak of water
700 or more (Baseline method)
S/N ratio for Raman peak of water
525 or more (Tangent method)
b. With emission-side spectral bandwidth set at 30 nm
S/N ratio for Raman peak of water
900 or more (Baseline method)
Wavelength: 350 nm, Time constant: 2.0 s
