Overview

Features

1. Fourier and Inverse Fourier Optical System

The Bettersizer 2600 is superior because it combines Fourier and inverse Fourier designs. This design allows for the detection of scattered light across a broad angular range from 0.016° to 165°. Additionally, unlike inverse Fourier design, particles do not need to be on a single plane, enabling accurate measurement of both small and large particles simultaneously.

Features of the Combination of Fourier and Inverse Fourier Design

• Spherical detector array: Forward, lateral, and backward detectors in 92 pieces in total
• Super large Fourier lens
• Small footprint: Compact design to save space

2. Intuitive and Powerful Software

• Fully automatic measurement routine
• Automatic cleaning routine
• Automatic data backup and highly customizable reports
• Direct conversion according to Fraunhofer and Mie evaluation models
• Switch between wet and dry dispersion modules with one click
• Intuitive user interface and orderly operation
• Real-time PSD curve for determining the optimal measurement conditions

Technology

Laser Diffraction. Image Credit: Bettersize Instruments Ltd.

Particle size distribution is a key factor in various applications involving powders or dispersions, such as construction materials (including cement and sand), pharmaceuticals, ceramics, colored pigments, fertilizers, emulsions, and others.

As applications diversify, there is a corresponding increase in the requirements for measurement methods, including broader size ranges, faster measurement times, and improved reproducibility.

Measuring particles near the extremes of their size range, especially when attempting to detect both small (in the nanometer range) and large particles (in the lower millimeter range) in samples with polymodal or broad distributions, poses significant challenges.

Nonetheless, contemporary laser diffraction particle size analyzers like the Bettersizer S3 Plus navigate these obstacles with an innovative optical system. This system excels in detecting backscattered light from very small particles and capturing large particles using an integrated high-speed CCD camera or through a synergistic approach combining laser diffraction and image analysis methods.
