纳米激光粒度仪采用动态光散射原理,其测试方法具有不破坏、不干扰纳米颗粒体系原有状态的特点,从而保证了测试结果的真实性和有效性。采用此原理保证了以下六点性能。

The principle of dynamic light scattering is adopted in nanometer laser particle size analyzer. The test method has the characteristics of not destroying or interfering with the original state of the nanoparticle system, thus ensuring the authenticity and validity of the test results. Using this principle, the following six properties are guaranteed.

  第一、大动态范围高速光子相关器:采用专利技术设计的光子相关器,以高、低速通道搭配的结构,有效解决了硬件资源与通道数量之间的矛盾,实现了1010的动态范围,并保证了相关函数基线的稳定性。

First, large dynamic range and high speed photon correlator using photon correlator design patent technology, the structure of high and low speed channel collocation, effectively solve the contradiction between the amount of hardware resources and channels, to achieve a dynamic range of 1010, and to ensure the stability of the baseline correlation function.

 

  第二、反演算法优:采用拟合累积反演法和基于V-曲线判断准则的正则化算法反演颗粒粒径及其粒度分布,使测量结果的准确度和重复性均小于1%。

Second, the optimal inversion algorithm: the optimal fitting cumulative inversion method based on V- curve and determine the regularization algorithm of particle size and particle size distribution standards, accuracy and repeatability of the measurement result is less than 1%.

 

  第三、抗噪能力强:采用小波消噪技术,解决了散射光强较低时,噪声过大对测量结果的影响。

Third, super noise immunity: the use of wavelet denoising technology to solve the scattering light intensity is too low, too much noise on the impact of measurement results.

 

  第四、稳定的光路系统:采用恒温532nm固态激光光源和单模保偏光纤技术搭建而成的光路系统,保证了光子相关光谱测量系统的稳定性和准确度。

Fourth 、 stable optical path system: the optical path system constructed by constant temperature 532nm solid-state laser source and single-mode polarization maintaining fiber technology ensures the stability and accuracy of the photon correlation spectrum measurement system.

 

  第五、高精度温控系统:基于半导体制冷装置,采用自适应PID控制算法,使温度控制精度达±0.1℃。

Fifth 、 high precision temperature control system: Based on the semiconductor refrigeration device, the adaptive PID control algorithm is adopted to make the temperature control accuracy reach to + 0.1.

 

  第六、纳米激光粒度仪www.jnwinner.com采用高灵敏度光子探测器:采用专业级高性能光电倍增管,对光子信号具有极高的灵敏度和信噪比。光子计数器采用边沿触发模式,瞬间捕捉光子脉冲的变化。

Sixth 、 nanometer laser particle size instrument www.jnwinner.com adopts high sensitivity photon detector: using professional high performance photomultiplier tube, the photon signal has very high sensitivity and signal to noise ratio. Photon counter uses edge triggered mode to capture the change of photon pulse instantaneously.
