Overview

Features

Measuring range:
Particle size from 0.01µm to 3500µm
Particle shape from 4µm to 3500µm

• Unique Dual Lens & Oblique Incidence Optical System(DLOIS): eliminates the fitting error of double beam system, enlarges detection angle (0.02 to 165 degree) and assures high sensitivity, resolution, and accuracy.

Automated Imaging analysis to provide particle shape information, especially useful for coarse particles; plus the ability to correlate particle size and shape analysis.

Auto refractive index measurement: ability to pre-determine the optical parameters of materials that will closer match the true value of the sample, enhancing the accuracy of the measurements of materials with unknown refractive index.

• Fully automatic operation minimizes workload as well as operation error.

• Measuring results of size and shape display in real time, rapidly track result changes with user-defined parameters.

Intelligent Particle Sizing Performance

Bettersizer S3 Plus defines a new era in particle sizing and shape measurement and a culmination of our years of experience excel in particle sizing and shape analysis instrumentation.

Accuracy

Resolution
Detection limit test : A mixture reference standard samples of 3.1 µm and 5.1 µm nominal diameter was used to gauge the resolution of the Bettersizer S3 Plus against the industry benchmark particle sizing instrument. The mixing ratio of 1.65 was used for the test. Bettersizer S3 Plus clearly out-resolve the benchmark instrument as shown in the following graphs.

Sensitivity
Test methodology: Measurement with a mix reference standard sample of 0.3mm, 0.85mm, and 3.5mm was performed against a benchmark instrument. Bettersizer S3 Plus resolves three peaks in the measurement result, while the benchmark instrument only able to resolve two peaks.
