LDY900 light-related nano-particle size analyzer
LDY900 is our latest nano-particle size analyzer based on the principle of dynamic light scattering. It uses high-speed digital correlator and a professional high-performance photomultiplier tube as the core device with the characteristics of fast, high resolution, repeatability and accuracy. It is the first choice for the determination of nanoparticle size.
The main performance characteristics:
Advanced Test Principle: The instrument uses the principle of dynamic light scattering and photon correlation spectroscopy to determine the particle size based on the rate of Brownian motion of the particles in the liquid. Small particle Brown fast motion, large particles Brown slow motion, laser irradiation of these particles, different sizes of particles will make scattered light speed fluctuations of different fluctuations. Photon correlation spectroscopy analyzes the particle size according to photon fluctuations in a particular direction. Therefore, the instrument has the principle of advanced, high precision features, thus ensuring the authenticity of the test results and effectiveness; is the first choice of nano-particle particle size measurement apparatus.
High sensitivity and signal-to-noise ratio: The instrument's detector uses a professional high-performance photomultiplier tube (PMT), photonic signal with high sensitivity and signal to noise ratio, thus ensuring the accuracy of test results;
Super computing power: The use of PCS technology to determine nanoscale particle size must be able to distinguish nanosecond-level signal fluctuations. The core components of the instrument using ASIC developed high-speed photon correlator, with a very high resolution 6ns recognition and high signal processing speed can be collected in real-time photon number and calculate the relevant operations, I set the test determined to respect basis.
Stable optical system: The optical system constructed with short wavelength LD pump laser source and optical fiber technology makes the photon correlation spectrum detection system not only small in size, but also has strong anti-interference ability, which lays the foundation for the accuracy of the test.
High-precision temperature control system: The precision of the temperature control system of the sample cell and the temperature control system of the laser is up to ± 0.1 ° C, so that the sample under test and the laser light source are in a constant temperature during the whole testing process to avoid the influence of the temperature change on the non-test result and ensure Test accuracy and repeatability;
Super-powerful analysis software: Inversion algorithm in analysis software uses the cumulative method recommended by international standards and the current more common non-negative least squares (NNLS) and Contin and other algorithms, the test results and the international authority of similar products With good consistency
Accurate and stable test: The perfect combination of high-performance hardware and internationally standardized inversion algorithm, which results in the accuracy and repeatability of the test results. The test accuracy and repeatability are all higher than those of international standards.
