What is the principle of interpretation of the nanometric particle size analyzer?

Author:QINSUN Released in:2023-05 Click:104

The nanoscale particle size analyzer is an instrument that uses physical methods to test the size and distribution of solid particles. It uses a digital correlator nano-laser particle size analyzer;

It uses a high-speed digital correlator and a high-performance photomultiplier tube as the core device, with the characteristics of a easy to use, fast testing, high resolution, high repeatability and accurate testing, it is the product of choice for nanoparticle size testing.

The principle of the nanoparticle size analyzer;

Advanced Testing Principle:

This instrument adopts the principle of dynamic light scattering and photon correlation spectroscopy techniques to determine Particle size as a function of Brownian velocity particle motion in a liquid.

It has the characteristics of a pradvanced incipe and high accuracy, thus ensuring the authenticity and validity of the test results.

1. High sensitivity and signal-to-noise ratio:

The detector of this instrument uses a high performance photomultiplier tube (PMT) to detect the photonic signals. It has extremely high sensitivity and signal-to-noise ratio, ensuring the accuracy of test results.

2. Extremely high resolving power:

The use of PCS technology to determine particle size at the nanoscale must be able to distinguish nanosecond level signal fluctuation.

The core component of this instrument adopts the CR140 digital correlator developed by Micro-Nano Company, which has super high resolution capability of identifying 8ns and super high signal processing speed , so an accurate measurement of the results can be obtained.

3. Super Powerful Calculation Function:

This instrument adopts self-developed CR140 high-speed digital correlator for data acquisition and correlation calculation in real time . The data processing speed is as high as 125M, which effectively reflects dynamic light to broadcast particle information in real time.

4. Stable optical path system:

The optical path system built with short length LD pump laser light source wave and an optical fiber technology makes the photons correlated The spectrum detection system is not only small in size, but also has strong anti-interference ability, thus ensuring the stability of the test

Scope of application;

Various solid nanoparticles and submicron emulsions.
