How Accuparan Works?

Product Description

Accuparan is a compact DLS instrument for particle sizing based on a novel optical approach to measure particles in the range of 1nm-5μm. A set of knowledge of optics, mechanics, electronics, software, and signal processing has been used in designing and manufacturing the device. Samples are placed inside the allocated part of the device, and measurement begins by illuminating a laser light on a colloidal sample. It efficiently suppresses multiple light scattering, so sample dilution is no longer required in most cases.


The illumination system is based on focal illumination, and the detection system is based on a microscopy system. Instead of illuminating the whole sample or large volume at once, laser light is focused onto a defined spot at a specific depth within the cell in microscopy. The combination of illumination and detection system increases the resolution, which reduces multiple scattering. Our system performs multiple angle measurements and changes the scattering angle within a certain range. Measurements at different scattering angles result in a simple and cost-effective system that provides a suitable level of sensitivity for many applications. Measurements at wider angles are preferred for higher sensitivity levels or more concentrated and polydisperse samples.


The software will be installed separately on a PC or laptop. Upon receiving the scattering data, the signal processing operation begins.

Analytical software inputs are:

  • User input data (mode / solution base)
  • Recorded scattering data
  • Device sensor data (temperature, scattering angle)

The software includes device settings, sample information, output display, data storage, reservation calendar, and scheduling data collection.
