Microtrac MRB CAMSIZER XL Image-Based Particle Size and Shape Analyzer

Overview

The Microtrac MRB CAMSIZER XL is a high-performance, dynamic image-based particle size and shape analyzer engineered for industrial R&D laboratories and quality control environments requiring robust, repeatable characterization of dry, free-flowing particulates. Operating on the principle of high-speed digital imaging combined with advanced edge-detection algorithms, the instrument captures silhouette projections of particles in free-fall or controlled dispersion, enabling simultaneous quantification of dimensional and morphological attributes without physical contact or sample preparation. Its validated measurement range of 160 µm to 135,000 µm (i.e., 0.16 mm to 135 mm) bridges a critical gap between conventional sieve analysis and laser diffraction—making it uniquely suited for coarse granules, agglomerates, catalyst pellets, foundry sands, pharmaceutical tablets, and mineral aggregates where both size distribution and geometric fidelity are process-critical.

Key Features

• Dynamic dry-particle analysis via gravity-fed or pneumatically assisted dispersion—eliminating solvent use, drying artifacts, or sedimentation bias.
• High-resolution monochrome CMOS camera system capturing up to 100 full-frame images per second at pixel-level resolution, ensuring statistically significant particle populations (>100,000 particles per run typical).
• Enclosed optical path with anti-static, dust-resistant housing and integrated air purge—designed for continuous operation in ambient lab or pilot-plant environments with minimal downtime for cleaning or recalibration.
• Modular sample introduction: interchangeable feed units support vibratory chutes, rotary feeders, and custom-engineered hoppers to accommodate bulk density, flowability, and friability variations across material classes.
• Automated optical self-cleaning protocol triggered by scheduled intervals or user command—reducing manual intervention and maintaining long-term measurement stability.
• Compliance-ready architecture: firmware and software support audit trails, electronic signatures, and configurable user roles aligned with GLP, GMP, and FDA 21 CFR Part 11 requirements when deployed in regulated settings.

Sample Compatibility & Compliance

The CAMSIZER XL accepts dry, non-cohesive to moderately cohesive powders and granules with minimal pre-treatment. It is routinely applied to ceramics, metal alloys, polymers, fertilizers, food ingredients, construction aggregates, and battery electrode materials. All shape descriptors—including sphericity, convexity, aspect ratio, and symmetry—are calculated in strict accordance with ISO 9276-6:2015 (“Representation of results of particle size analysis — Part 6: Descriptions and quantitative analysis of particles”), ensuring cross-laboratory comparability. Optional calibration verification kits traceable to NIST SRM standards are available for routine performance qualification (PQ) and operational qualification (OQ).

Software & Data Management

CAMSIZER Control Software v5.x provides intuitive workflow management—from method setup and real-time imaging feedback to batch reporting and statistical comparison. Each analysis generates a comprehensive data package including cumulative and differential size distributions, multivariate shape histograms, scatter plots (e.g., sphericity vs. circularity), and 3D morphology heatmaps. Raw image archives, metadata logs, and operator annotations are stored in encrypted SQLite databases compliant with ISO/IEC 27001 information security frameworks. Export options include CSV, PDF, XML, and direct integration with LIMS via ODBC or RESTful API interfaces.

Applications

• Pharmaceutical solid dosage development: correlating tablet granule morphology with compressibility and dissolution kinetics.
• Mineral processing optimization: evaluating crushing/grinding efficiency through changes in convexity and surface roughness.
• Additive manufacturing feedstock qualification: verifying spherical consistency and detecting satellite formation in metal powders.
• Foundry sand quality assurance: monitoring angularity and grain roundness to predict mold strength and surface finish.
• Food texture engineering: linking particle elongation and aspect ratio to mouthfeel and rehydration behavior in instant beverages.
• Environmental particulate source tracing: differentiating natural vs. anthropogenic origin using multi-parameter shape fingerprints.

FAQ

What particle size range is validated for ISO-compliant reporting?
The CAMSIZER XL delivers traceable measurements from 160 µm to 135,000 µm; lower limits are constrained by optical resolution and particle settling velocity, not algorithmic interpolation.
Can the system analyze wet or slurry-based samples?
No—this is a dedicated dry-particle imaging platform. For liquid suspensions, Microtrac MRB recommends the S3500 laser diffraction series or the Sync™ hybrid system combining static imaging with dynamic light scattering.
How is measurement reproducibility verified across operators?
Built-in reference standards (glass microspheres, calibrated grits) enable daily system suitability checks; inter-operator variance is typically ≤2.3% RSD for D50 under standardized SOPs.
Is remote diagnostics and software update support available?
Yes—via secure TLS-encrypted connection, authorized service engineers can perform firmware validation, parameter optimization, and troubleshooting without on-site visits.
Does the instrument meet CE and UL safety certifications?
Yes—the CAMSIZER XL carries full CE marking (2014/30/EU EMC Directive, 2014/35/EU Low Voltage Directive) and UL 61010-1 certification for laboratory electrical safety.
