Nano particle Size Analyzer (180 x 300 x 260 mm)

Nano particle Size Analyzer is a highly flexible nano particle size analyzer based on Dynamic Light Scattering (DLS) which provides information on particle size, concentration, and molecular weight. It allows faster measurements with reliable technology, higher precision, and better accuracy. All of this combined into a compact DLS analyzer with a revolutionary fixed optical probe.

With the unique and flexible probe design and the use of the Laser Amplified Detection method in the Nano particle Size Analyzer the user is able to choose an appropriate vessel as a measurement cell to satisfy the needs of any application. This design also allows measurements of samples over a wide concentration range, monomodal or multimodal samples, all without prior knowledge of the particle size distribution. This is made possible through the use of the Frequency Power Spectrum (FPS) method instead of classical Photon Correlation Spectroscopy (PCS).

FUNCTIONAL PRINCIPLE

The optical bench of the nano particle size analyzer Nano particle Size Analyzer is a probe containing an optical fiber coupled with a Y splitter. Laser light is focused on a volume of sample at the interface of the probe window and the dispersion. The high reflectivity sapphire window reflects a portion of the laser beam back to a photodiode detector. The laser light also penetrates the dispersion and the particle–s scattered light reflects at 180 degrees back to the same detector.
