Laboratory Fluorescence Spectrophotometer Types with Cheap Price
1. 1200 line diffraction grating emission monochromator . Its large aperture and non-spherical reflecting mirrors produces extra high sensitivity.
2. LED is a cold-light source with longevity, lower background & reliability, prevent from thermo-pollution.
3.Automatic zero adjustment and automatic background subtraction,
4. Eight stage sensitivity adjustment, Real time fluorescence value display and concentration print out,.Extra wide dynamic range of fluorescence value ensures accurate measurement of minute changes in micro samples.
Applications
Fluorescence analysis is a high sensitive and high selective sophisticated analytical method.
This method can provideinformation including excitation and emission spectrum, emission light intensity and measurement of life of emission lightand polarization fluorescence etc. This method can provide a wide lineal range of working curve.It has becoming animportant analytical method in the region of trace analysis.
This method has been used in:
1.Medical science and clinical analysis Clinical analysis of biological specimen.
2.Pharmaceutical science and pharmacology Analysis ofnatural pharmaceutical products; Quality control ofpharmaceuticals and research of pharmaceuticalmetabolites.
3.Biochemistry Analysis of minute quantity of substances in biological body.
4.Food industry Analysis of minute quantity of constituents in food.
5.Pollution analysis Atmospheric pollution, environmental testing and food contamination analysis.
6.Organic and inorganic chemistry Used in the trace analysis in case of those substances cannot be determined byabsorption spectrophotometry.
Features
1.Two operation modes could be chosen: fluorescence intensity and luminous intensity. Fluorescence scanning,kinetic determination and quantity analysis could be done under fluorescence intensity mode.
2.365nm exciting wavelength,Raman peak of water S/N ≥150 High performance sensitivity simplifies themeasurement of low detective sample.
3.10 stages gain adjustment could be chosen for emission spectrum scanning, including high speed low S/N scanningand precise scanning. Total spectrum scanning could be done in 1 second. With the intelligent pre scanningfeature, unknown sample"s spectrum information could be detected rapidly. Auto-omission of the influence ofscattering peak and harmonic peaks, it ensure the best measurement parameters and locate the fluorescenceemission peak.
4. Support off-line mode and on-line mode. Under off-line mode, instrument"s computer system offer the fluorescenceintensity measurement,
