TP-NM10000 is our company's latest nano particle size analyzer based on the principle of dynamic light scattering. It uses a high-speed digital correlator and a professional high-performance photomultiplier tube as the core device. It has the characteristics of fast, high resolution, repeatability and accuracy. It is the first choice for nano particle size determination.
Main performance characteristics:
Advanced testing principle: This instrument uses dynamic light scattering principle and photon correlation spectroscopy technology to determine the particle size according to the Brownian motion speed of the particle in the liquid. The Brownian motion of small particles is fast, and the Brownian motion of large particles is slow. When laser irradiates these particles, particles of different sizes will cause the scattered light to fluctuate at different speeds. Photon correlation spectroscopy analyzes the particle size based on the fluctuation of photons in a specific direction. Therefore, this instrument has the characteristics of advanced principle and extremely high precision, thus ensuring the authenticity and validity of the test results; it is the first choice for measuring the particle size of nano-excited particles.
High sensitivity and signal-to-noise ratio: The detector of this instrument uses a professional-grade high-performance photomultiplier tube (PMT), which has extremely high sensitivity and signal-to-noise ratio to photon signals, thereby ensuring the accuracy of the test results;
Extremely high resolving power and super computing function: using PCS technology to determine the size of nanometer particles, it must be able to distinguish nanosecond signal fluctuations. The core component of this instrument adopts a high-speed photon correlator developed by an application specific integrated circuit ASIC. It has a very high resolution of 6ns and a very high signal processing speed. It can collect the number of photons and calculate related operations quickly and in real time.
Stable optical path system: The optical path system built with short-wavelength LD pump laser light source and 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 ±0.1ºC, so that the tested sample and the laser light source are kept in a constant temperature state during the entire test process, avoiding the influence of temperature changes on the test results and ensuring The test is accurate and repeatable;
Super-functional analysis software: The inversion algorithm in the analysis software adopts the cumulative measurement method recommended by international standards and the current more common non-negative least squares (NNLS) and Contin and other algorithms. The test results are similar to those of international authoritative similar products Have good consistency;
Accurate and stable testing: The perfect combination of high-performance hardware and internationally standardized inversion algorithms creates the accuracy and repeatability of the TP-NM10000 test results. Its test accuracy and repeatability are all higher than international standards.
