Features and Benefits

•Dual Lens & Oblique Incidence Optical System (DLOIOS)
By adding a second lens behind the sample cell and applying the oblique incidence laser structure, DLOIOS increases system reliability and reduces cost by fully utilizing the capabilities of a single diode laser.

•Particle size and 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:
Improve the accuracy of measurements of materials with unknown refractive index.

•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 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 3.1µm and 5.1µm 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-resolves 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.
