Dynamic light scattering (DLS), also known as photon correlation spectroscopy (PCS), is a commonly used characterization method for nanoparticles. The DLS particle size analyzer has the advantages of accuracy, rapidity, and good repeatability for the measurement of Nano particles, emulsions or suspensions. Nanoptic 90 nano particle size analyser is a typical nanoparticle size measurement instrument based on dynamic light scattering.It can measure nanomaterial down to 1 nanometer which is an essential tool for nanoparticle size distribution measurement to understand and research nano powdered materials.
The Nanoptic 90 Plus is capable of measuring the particle size distribution of nanoparticles based on the principle of dynamic light scattering. This system includes an instrument and a computer system which performs measurements in the following principles:
The Nanoptic 90 Plus nanoparticle size analyzer designed to be a 90° dynamic light scattering optical system. The vertically polarized laser enters the sample cell after being reflected by two mirrors. In the optical path, an intensity attenuator module is used to adjust the incident intensity. The sample is placed in a high-precision temperature-controlled sample holder, and then the optical fiber-connected APD detector collects the scattering intensity of the sample at 90°. The scattered signals are processed by the software to provide the particle size and size distribution information of the sample.
