Fluorescence Spectrophotometer, Model DW-F96PRO , DRAWELL (CAT#: STEM-S-0059-CJ)

Fluorescence analysis is a highly sensitive and high selective sophisticated analytical method. This method can provide information including excitation and emission spectrum, emission light intensity and measurement of life of emission light and polarization fluorescence, etc. This method can provide a wide linear range of the working curve. It has become an important analytical method in the region of trace analysis.

Two operations modes could be chosen: fluorescence intensity and luminous intensity. Fluorescence scanning, kinetic determination, and quantity analysis could be done under fluorescence intensity mode.
High-performance sensitivity simplifies the measurement of low detective sample: 365nm exciting wavelength， Raman peak of water S/N≥150.
10 stages of gain adjustment could be chosen for emission spectrum scanning, including high speed low S/N scanning, and precise scanning. Total spectrum scanning could be done in 1 second. With the intelligent pre-scanning feature, unknown sample spectrum information could be detected rapidly. Auto-omission of the influence of scattering peaks and harmonic peaks ensures the best measurement parameters and locates the fluorescence emission peak.
Support off-line mode and online mode. Under off-line mode, the instrument’s computer system offers the fluorescence intensity measurement, concentration direct reading, auto 0 adjustment, auto background subtraction and etc. Under online mode, we could use quality and quantity software to control data acquisition and analysis through the USB2.0 interface.
High stable and long-life 150W xenon lamp and power source ensures high stable testing and a wide range of the spectrum.
The normalized feature for fluorescence value could make different fluorescence results comparable.
Provide optional PC qualitative and quantitative software package with expansible time scanning, wavelength scanning, graphic calculation, and storage-access abilities.
Optional accessories for different measurements, including single hole cell holder, fluorescence sample holder for different features, 200μl micro-scale centrifuge tube, microscale capillary sample holder, semi-auto sample introduction accessories, membrane sample accessories, powder sample accessories, jacket sample accessories and etc.
