Description
Fluorescence Spectrophotometer
Brief Introduction
SP-LF97 fluorescence spectrophotometer is a new generation of high performance molecular luminescence analysis instrument. The Pduct structure is exquisite, has the characteristics of high detection sensitivity, fast scanning speed, wide spectrum measuring range, high dynamic range, fast 3D scanning, and so on. Easily meet the requirements in the field of material research, pharmaceutical analysis, biochemical and clinical testing, water quality analysis and control, food safety testing (dairy Pducts, aquatic Pducts, such as vitamin C, selenium, aflatoxin), and other areas.
Main Features
High sensitivity: based on high efficiency optical design and weak signal detection technology, the water Raman peak signal to noise ratio can be greater than 200 (P – P) to the leading domestic and international advanced level.
High scanning speed: the high speed digital signal Pcessing unit Pvides the world’s fastest scanning speed at 48000nm/min. Only 1 second to get classic fluorescence spectra, 1 minute to get high quality of three-dimensional fluorescence spectra.
Wide Spectral measurement range: using a double monochromator design, excitation and emission wavelength range covering 200nm to 900nm, meet the needs of most fluorescence analysis.
Excitation light path monitoring system: instrument is equipped with excitation light dual beam ratio monitoring system to ensure the fluorescence signal high and stable.
High quality assurance: using Hamamatsu’s high quality Xenon light source and photoelectric multiplier tube detectors and instruments to Pvide sufficient light intensity signal and the detection sensitivity.
Built-in optical gate: Built-in optical gate, designed for unstable sample
