Overview

Features and Benefits

Measuring range:
Particle size from 0.01μm to 3500μm.
Particle shape from 2μm to 3500μm.

Dual Lenses & 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.

Particle size & shape: two CCD cameras with 120 fps, 1.3 Mpixel, and lenses 0.5x and 10x. It can combine particle size and shape (0.5x), separate 0.5x or 10x image, 0.5x and 10x joint image to measure particle shape.

Refractive index measurement: pre-determine the refractive index of materials; improve the accuracy of measurements of materials with unknown refractive index data.

Ease of use: with Standard Operation Procedure (SOP), automatic alignment, automatic circulation & dispersion system, and the powerful software, sample analysis on Bettersizer S3 Plus can be a one-button operation.

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
The accuracy of Bettersizer S3 Plus as verified by measurements of eight standard samples.

Repeatability
Bettersizer S3 Plus measures samples with a wide distribution range. Six repeat measurement results under same analysis conditions yield good repeatability as shown in the following graph. Average repeatability deviation of D50 is 0.31%.

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.
