Laser particle size analyzer Bettersizer 2600 Plus

opticaldynamic image analysislaser diffraction

Overview
Bettersizer 2600 Plus combines laser diffraction and dual-camera dynamic imaging on a single modular platform to deliver both particle size and particle shape characterization. The instrument supports flexible wet and dry dispersion modules so one system can be configured for diverse sample types, volumes and solvents. It provides fast, repeatable particle size distributions using a high‑performance laser diffraction optics and captures high‑speed particle images to quantify size and shape and to provide visual evidence of agglomerates, irregular particles and oversized tails.

Features and Benefits

• Size and Shape in One Platform: combination of laser diffraction and dynamic imaging
• Wide Range: 0.02–3500 µm for combined configurations (laser diffraction nominally covers the fine-to-coarse range; combined imaging extends the upper limit)
• Modular Dispersion Units: flexible wet & dry setups for different samples and solvents

Advanced Laser Diffraction System

• Wide-angle signal collection to improve PSD reliability and robustness
• Patented Fourier and inverse-Fourier optical system for enhanced signal capture
• 92-detector array for high-quality scattering detection
• Angular coverage approximately 0.016°–165° for fine and coarse particles
• Tilted sample cell design to reduce total internal reflection and improve signal utilization
• Patented refractive-index measurement capability to increase confidence with optically challenging samples

Performance Highlights

• Laser diffraction measurement range (typical instrument configuration): from the submicron region to the coarse particle domain (fine resolution to 0.02 µm with appropriate configuration)
• Combined platform capability up to 3500 µm when imaging module is added
• Measurement speed: complete measurements in as little as ~10 s (application dependent)
• Accuracy and repeatability targets: stated better than ~0.5% under appropriate test conditions

Dual-Camera Dynamic Imaging (PIC-1) — real-time particle imaging

• Modular dual-camera imaging module for real-time particle image acquisition during measurement
• Operates in imaging-only or combined (imaging + laser diffraction) modes
• Captures high-speed particle images and reports extensive size and shape parameters (up to dozens of descriptors)
• Size range for imaging: approx. 2–3500 µm (depending on magnification and optics)
• Available magnifications: e.g. 0.5× and 10× (selectable)
• High frame rate imaging (example: up to ~70 fps) to capture particles in flow
• Provides visual traceability for oversized particles, agglomerates and rare events to support QC and troubleshooting

Modular Dispersion & Workflow Flexibility

• Support for a broad selection of wet and dry dispersion units to accommodate different sample types and solvents
• Single-instrument modular design enables lab consolidation of multiple measurement workflows

Software & Results

• Integrated data handling that merges size and shape results and supports review of particle images for traceability
• Reports a comprehensive set of size and shape parameters for single-particle analysis and statistical summaries
