Fluorescence Spectrophotometer Model : LI - 4200

About Fluorescence Spectrophotometer Model : LI - 4200

fluorescence spectrophotometer is a new generation of high performance molecular luminescence analysis instrument. The product 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 products, aquatic products, 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 150 (P - P). High scanning speed: the high speed digital signal processing unit provides the world's fastest scanning speed at 48000nm/min. Only about 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 200 nm to 900 nm, 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 Hamamatsuis high quality Xenon light source and photoelectric multiplier tube detectors and instruments to provide sufficient light intensity signal and the detection sensitivity. Built-in optical gate: Built-in optical gate, designed for unstable sample. 


Functions

• Spectrum Correction: Adjusts for non-uniform lamp output and detector sensitivity to provide true, accurate spectra.
• Sensitivity Control: Modern units like the Agilent Cary Eclipse use automatic gain control to optimize signals across a wide dynamic range, allowing the detection of  nanogram-level concentrations.
• Advanced Measurements: Can be used for time-resolved fluorescence (studying molecular dynamics) and anisotropy (measuring molecular rotation and binding)

 

Exceptional Speed and Sensitivity

The LI-4200 model offers outstanding scanning speeds, reaching up to 48,000 nm/min for swift throughput. Its high sensitivity, combined with dual monochromators and 90 optical arrangement, delivers precise and reliable results. This ensures the detection of even the faintest fluorescence signals, essential for accurate trace analysis and molecular studies.


Intuitive User Interface

Operating the LI-4200 is remarkably straightforward thanks to its advanced graphic LCD or color touchscreen display. Users can easily control the spectrophotometer, adjust scanning parameters in real time, and monitor ongoing analyses to ensure optimal performance for various applications, including light absorption and emission measurements.


Robust, Versatile Design

With its compact square shape, lightweight construction, and robust dimensions (380445310 mm), the LI-4200 fits seamlessly into any laboratory setting. It is powered via AC 220V/50Hz or 110V/60Hz, making it adaptable to standard lab power sources, while its white exterior and ergonomic form factor prioritize both style and function.
