Professional Supplier of Laboratory Scientific Instruments
The FSP-390 fluorescence spectrophotometer is a high-end research molecular fluorescence product that can achieve high-speed three-dimensional scanning and phosphorescence testing. Its core components are selected from well-known foreign suppliers. The product has stable performance, powerful functions, easy operation, sensitivity, the main indicators such as signal-to-noise ratio have reached the level of similar foreign products, and are widely used in teaching and scientific research, food safety testing, materials research, environmental monitoring and other fields. It is suitable for customers with a wide range of sample testing and high-performance index requirements.
(1) Bringing together a variety of spectroscopic technologies
It has lower stray light, higher resolution (1200L/mm), and better test resolution (better than 1.0nm).
The chopper system adopts a unique design structure, and the control system uses multi-CPU division of labor and collaboration to achieve high-precision control of the chopper system and ensure the accuracy of phosphorescence measurement. Phosphorescence measurement takes advantage of the long life of phosphorescence to completely avoid the interference of Rayleigh light, Raman light and stray light. It is the most effective trace measurement method.
Measures phosphorescence lifetimes as short as 1ms and can be applied to a variety of sample types
The fluorescence three-dimensional scanning function can quickly locate the fluorescence information of unknown samples. High-speed scanning can shorten the analysis time of unknown samples and improve work efficiency. Colorful three-dimensional spectra can add artistic color to academic papers
It can realize constant wavelength synchronous fluorescence spectrum scanning of the tested sample. Constant wavelength synchronous scanning can reduce the overlapping phenomenon of fluorescence peaks when measuring multi-component samples, narrow the spectrum and reduce the influence of scattered light.
(2) High sensitivity, high speed and high reliability
The unique optical system design, combined with digital signal processing technology, can achieve a signal-to-noise ratio of more than 300:1 (P-P), easily meeting the testing needs of high-resolution and ultra-micro samples.
The unique horizontal slit design is applied to both the excitation and emission beams, improving detection sensitivity while reducing the amount of sample extraction required. A 10mm standard cuvette only requires 0.5mL sample.
The scanning speed is as high as 60000nm/min. Combined with the advanced data acquisition system, rich data points can be obtained during high-speed scanning to ensure the authenticity and accuracy of the test spectrum.
The excitation side is equipped with a light-blocking shutter to reduce sample exposure time and protect photosensitive samples; the emission side is equipped with a gated shutter to prevent the receiver from being directly exposed to strong light and extend the service life of the receiver.
(3) Automatic deozone function
Use long-life automatic deozone xenon lamp to ensure laboratory air quality; long-life xenon lamp to reduce the frequency of xenon lamp replacement
(4) Excellent ease of use
The software workstation has a dual background subtraction function. During sample testing, select different buttons according to different test backgrounds to achieve the purpose of subtracting your own background. The software can directly calculate the fluorescence intensity and concentration of the solution to be tested.
Can be equipped with a variety of practical accessories, from solid sample holders, automatic eight-link sample cell holders, water bath constant temperature magnetic stirring sample cell holders, polarization accessories to fluorescent water bath constant temperature systems, to help customers solve a variety of application analysis problems
The supporting software of the instrument has the function of "three-level management authority" and meets the testing requirements of the National Pharmacopoeia.
