Automatic Laser Nanoparticle Size Analyzer

Main Performance Features:

Advanced testing principle: This instrument uses the dynamic light scatering principle and photon correlationspectroscopy technology to determine the particle size according to the speed of the Brownian motion of the particlesin the liquid. The Brownian motion of small particles is fast, and the Brownian motion of large particles is slow.When laser light iradiates these particles, particles of different sizes will cause the scattered light to fluctuate atdiferent speeds. Photon correlation spectroscopy analyzes the particle size according to the fluctuation of photonsin a specific direction. Therefore, this instrument has the characteristics of advanced principle and high precision, thus ensuring the authenticity and validity of the test results, it is the preferred instrument for particle size determination of nano-excited particles

High sensitivity and signal-to-noise ratio: The detector of this instrument adopts professional-grade high-performance photo multiplier tube(PiT), which has extremely high sensitivity and signal-to-noise ratio to photon signals, thus ensuring the accuracy of test results;

Extremely high resolving power and powerful computing function: Using PCS technology to determine the sizeof nano-scale particles must be able to distinguish nano-second signal fluctuations. The core component of this instrument adopts a hiah-speed photon correlator developed by an application-specific intearated circuit ASlC.which has a very high resolution capability of 6ns and a very high signal processing speed, which can quickly collect photons in real time and calculate related operations. Base.

Stable optical path system: The optical path system constructed with short-wavelength LD pump laser light source and optical fiber technology makes the photon correlation spectrum detection system not only small in size, but also has strong anti-interference ability, thus ensuring the stability of the test.

High-precision temperature control system:The accuracy of the sample cell temperature control system and the laser temperature control system is as high as ±0.1 °C,so that the tested sample and the laser light source are kept at a constant temperature during the entire test process, avoiding the influence of temperature changes on the test results.ensuring that Testing is accurate and repeatable.

Super powerful analysis software: The inversion algorithm in the analysis software adopts the cumulant methodrecommended by international standards, as well as the commonly used non-negative least squares (NNLS) and Contin algorithms. have good consistency;

Accurate and stable testing: The perfect combination of high-performance hardware and interationally standardizedinversion algorithms has created the accuracy and repeatability of Nano90 test results. lts test accuracy and repeatabilityare higher than the requirements of international standards.
