Product Description Product DescriptionWinner802/80 dynamic light scattering nanometer particle size analyzer which based on the dynamic lightscattering principle, and also 1st one which use digital correlator in China. And It's upgrade fromWinner801, which is 1st set of Nanometer particle size analyzer. Based on Brownian motion principle,smaller particle, faster speed, bigger particle, more slowly. It adopt great performance of JapanHAMAMATSU photomultiplier and self-developed high speed digital correlator as core parts, Getdiffusion coefficient by test scattering light change in some angle, and calculate particle diameter anddistribution according to stokes-Einstein equation. the machine is with characters of fast calculation, highresolution ration, good accuracy and repeatability, therefore it's widely used in company product labresearch and university use.Main Features:1) Advanced test principle:Dynamic light scattering principle and photon correlation spectrum technology, according to Brownianmotion speed of particle to test particle size, different size of particles have different speed, when laserilluminate these particles, it will make scattering light happen different speed of fluctuations- downs.Photo correlation spectrum method will analyze these particle size according to Photon fluctuations-downs in particular direction. 2) High resolution:Using PCR technology test nanometer-scale particle size, must be able to distinguish nanosecond signalfluctuations. The core components of the instrument is CR256 digital correlator developed by ourcompany, with 8ns high resolution speed. 3) High sensitivity and Noise-signal ratioDetector is composed of imported HAMAMATSU photomultiplier, so ensure good accuracy. 4) High speed data collection and calculationSelf-developed patent product-CR256 digital correlation, It could finish dynamic scattering lightintensity collection and autocorrelative function real time calculation, Data processing speed is up to162M, effectively reflect dynamic scattering light information of different sizes of particles. 5)High stable optical path systemPhoton correlation spectrum detect system adopt optical-fibre technology, smaller size and highanti-interference and reliability. 6)High precision constant temperature control systemSemiconductor temperature control technology, precision control within ±0.1oC,make samples be in aconstant state throughout the testing process, prevent testing error because temperature change willchange liquid viscosity and Brownian movement speed. 7) Output parameters: Real particle size distribution, freely set D10-D100, D[4,3],D[3,2], D[2,1],D[1,0]and specific surface areaMODELWINNER 802StandardGB/T 19627-2005/ISO 13321:1996GB/T 29022-2012/ISO 22412:2008Measure range1nm-10000nmConcentration range0.1mg/ml--100mg/mlAccuracy error<1%( CRM D50)Repeatability error<1% ( CRM D50)Light sourceSemiconductor laser λ= 532nm P=30mWDetectorImported Japan HAMAMATSU photo-multiplier (19-90oC)Scattering angle90oSample cuvette1-4mLTest temperature5-40 oC(temperature controller 5-90oC, precision within 0.1oC)Test speed<5 MinPower Supply220V 50HZ/60HZOuter DimensionL48cm*W27cm*H17cmG.W.12KgOperation systemWin XP/Win 7/Win 10 64 bits, USB port: 2.0 /3.0AnalysisAverage particle diameter, particle distribution,photon counting rate etc.Digital CorrelatorModelCR256Auto-correlation channels256Baseline channel4Physical channels5000Unit delay time100ns-10ms Hot seller Company Profile Production Process Packaging & Shipping
