DW-F97 Series Fluorescence Spectrophotometer
DW-F97 fluorescent spectrophotometer is a new generation of high-performance molecular luminescence analysis instrument. The product structure is exquisite and 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 products, aquatic products, such as vitamin C, selenium, aflatoxin), and other areas.
Features of DW-F97 Fluorescent Spectrophotometer
- 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 processing unit provides the world’s fastest scanning speed at 48000nm/min. Only 1 second to get classic fluorescence spectra, and 1 minute to get high-quality three-dimensional fluorescence spectra.
- Wide Spectral measurement range: using a double monochromator design, excitation and emission wavelength range covering 200 nm to 900 nm, meet the needs of most fluorescence analysis.
- Excitation light path monitoring system: the instrument is equipped with an excitation light dual beam ratio monitoring system to ensure the fluorescence signal is high and stable.
- High-quality assurance: using Hamamatsu’s high-quality Xenon light source and photoelectric multiplier tube detectors and instruments to provide sufficient light intensity signal and detection sensitivity.
- Built-in optical gate: Built-in optical gate, designed for unstable samples.
