Advantages

• Automatic optical bench alignment using hybrid stepper motor with micron-level positioning for stable, reproducible optical paths.
• Professional dry dispersion system reproducing native particle state via controlled pneumatic dispersion; stable airflow reduces agglomeration and improves repeatability for metal powders, new energy materials, ceramics, cement and additive manufacturing powders.
• Modular dry/wet dispersion design with automatic sample introduction shortens pipeline length, prevents large-particle sedimentation, simplifies cleaning and reduces maintenance.
• Unconstrained free-fitting software collects scattering data and automatically analyzes multimodal particle groups; high resolution for particles below 2 μm (verified across 12 size grades).
• Patented inverse Fourier folded optical path provides 0.015–145° detection angle range, expanding measurement range and resolution; sealed optical path improves dust protection.

Application
Suitable for cement, ceramics, pharmaceuticals, dyes, pigments, chemicals, catalysts, brazing materials, dust, additives, pesticides, explosives, graphite, photosensitive materials, fuels, metal and non-metal powders, calcium carbonate, kaolin, coffee and other powders. Especially valuable when liquid-based measurement alters material chemistry, shape or causes losses, and for materials with wide distributions or large particle sizes such as certain herbal medicines and magnetic materials.

Patent & Technology Highlights
Includes patented technologies: optical bench design, 3D optical bench alignment, application of Mie scattering, sealed sample cell design for dry analyzers, orthogonal dual-beam laser application, powder dispersion pump design and wet circulation installation.

Test Report & Outputs
Reports exportable in Word, Excel, image, text and PDF formats to support viewing, data reprocessing and citation.
