Perkin Elmer 200 Series Fluorescence Detector (FLD)

Specification
Optical system Ratio photometry; intensity of transmitted beam is monitored.
Light source Xe lamp (150 W)
Hg lamp (for checking wavelength)
Measuring wavelength range Excitation wavelength 200 to 850 nm/Zero order
Measuring wavelength range emission wavelength 250 to 900 nm/Zero order
Photomultiplier must be changed at emission wavelength greater than 731 nm
Spectral bandwidth excitation side 15 nm
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
Wavelength setting By communication (E-line) or keyboard
Wavelength accuracy ±3 nm
Wavelength repeatability ±0.5 nm
Recorder output (option) 10 mV full-scale; full scale range 1 to 1000 settable in increments of 1
Processor output (option) 1 V full-scale -40 to 1000 mV
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
Sensitivity a. With emission-side spectral bandwidth set at 15 nm
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
Auto Zero range 0 to 1000
Offset range 0 to 1000 (settable in steps of 1)
Time program Number of programs 9
