Features
◆Two operation mode could be chosen: fluorescence intensity and luminous intensity. Fluorescence scanning, kinetic determination and quantity analysis could be done under fluorescence intensity mode.
◆365nm exciting wavelength Raman peak of water in 1 cm quartz fluorescence cuvette S/N≥150 High performance sensitivity simplifies the measurement of low detective sample.
◆10 stages 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's spectrum information could be detected rapidly. Auto-omission of the influence of scattering peak and harmonic peaks, it ensure the best measurement parameters and locate the fluorescence emission peak.
◆Support off-line mode and on-line mode. Under off-line mode, instrument's computer system offer the fluorescence intensity measurement, concentration direct reading, auto 0 adjustment, auto background subtraction and etc. Under on-line mode, we could use quality and quantity software to control data acquisition and analysis through USB2.0 interface.
◆High stable and long life 150W xenon lamp and power source ensure high stable testing and wide range of spectrum.
◆The normalized feature for fluorescence value could make different fluorescence's result 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 measurement, including single hole cell holder, fluorescence sample holder for different features, 200μl micro scale centrifuge tube, micro scale capillary sample holder, semi-auto sample introduction accessories, membrane sample accessories, powder sample accessories, jacket sample accessories and etc.
