Product overview
The SP-LF97 series is a molecular fluorescence spectrophotometer available as SP-LF97, SP-LF97PRO and SP-LF97XP. A double monochromator design covers excitation and emission wavelengths from 200 to 900 nm, with a 150 W Hamamatsu xenon lamp and photomultiplier detector, and selectable 2, 5, 10 and 20 nm slits.
Scanning reaches 48,000 nm/min, so a standard fluorescence spectrum takes about one second and a 3D spectrum about one minute. The SP-LF97XP offers ±0.4 nm wavelength accuracy, a water Raman S/N of 200 or more (P-P) and a detection limit of 5×10⁻¹¹ g/mL quinine sulfate, while the SP-LF97 and SP-LF97PRO provide ±1.0 nm and 1×10⁻¹⁰ g/mL. A dual beam ratio monitor stabilises the excitation signal and a built-in optical shutter protects light-sensitive samples.
Applications include materials research, pharmaceutical analysis, biochemical and clinical testing, water quality monitoring and food safety testing such as vitamin C, selenium and aflatoxin.
