Hydro Insight for Malvern Mastersizer 3000 Particle Size Analyzers

The Hydro Insight accessory provides dynamic image analysis (DIA) for Malvern Panalytical Mastersizer 3000 particle size analyzers. Developed in conjunction with Malvern Panalytical this is installed inline with the wet dispersion systems.  The Hydro Insight generates real-time particle images, shape metrics, and concentration measurements using the same circulating sample used for laser diffraction.  This ensures that complementary data from the Hydro Insight is given on the same aliquot of sample analyzed with the Mastersizer 3000.

The combination of laser diffraction (size distribution) and dynamic imaging (size, shape, count and concentration) delivers a more complete understanding of particle behavior—especially for polydisperse materials, samples with agglomerates, or materials whose morphology affects performance.


Why Add a Hydro Insight to the Malvern Mastersizer 3000?

Laser diffraction provides fast, repeatable particle size distributions (PSD). However, diffraction data alone cannot reveal:

  • Whether large particles are true single particles or agglomerates

  • Whether fine particles are being masked by coarse particles

  • Whether bubbles, fibers, or foreign contaminants are present

  • Whether changes in PSD are due to dispersion, breakage, or process variation

The Hydro Insight addresses these limitations by supplying direct visual confirmation and shape-based interpretation of the sample under the same dispersion conditions used by the Mastersizer.


Dynamic Imaging Reveals Particles Laser Diffraction May Miss

Dynamic image analysis is particularly effective for identifying:

  • Sub-populations of small particles not visible in volume-weighted laser diffraction

  • Agglomerates versus primary particles

  • Non-spherical particles (e.g., flakes, needles, platelets)

  • Bubble contamination or air entrainment

  • Foreign particles in quality control environments

The Hydro Insight provides number-weighted size distributions that complement the volume-weighted laser diffraction data from the Mastersizer 3000.

How the Hydro Insight Works with Mastersizer Particle Size Systems

Hydro Insight is installed as an inline flow cell connected to the Mastersizer’s Hydro series wet dispersion units. During a standard measurement:

  1. The dispersion unit circulates the sample through the Hydro Insight flow path.

  2. The onboard camera captures images of particles in motion at high frame rates.

  3. Software extracts particle size, shape, count, and morphology descriptors.

  4. Results are displayed alongside the Mastersizer’s diffraction PSDs for comparison.

This integration allows operators to evaluate dispersion quality, sample stability, and particle morphology without altering existing measurement protocols.


Real-Time Particle Images and Morphology Analysis

Hydro Insight provides:

  • High-resolution particle thumbnails for visual confirmation

  • Morphology distributions based on 32+ parameters
  • Automated classification of particle types (e.g., agglomerates vs. primaries)

  • Counts per mL and total particle concentration

  • Correlation tools linking PSD to shape trends

These outputs enable deeper root-cause analysis in R&D, QC, and troubleshooting.

Key Features for Mastersizer Users

Wide Effective Measurement Range

Two magnification options allow broad applicability:

  • Standard magnification: ~1–300 µm

  • Low magnification: ~10–800 µm

This supports materials from fine powders to coarse particulates.

High Frame Rates and Large Sample Statistics

Dynamic imaging captures large numbers of particles, improving number-based statistics and supporting heterogeneous materials.

Shape Parameters Derived from Each Particle

Examples include:

  • Aspect ratio

  • Circularity

  • Elongation

  • Convexity

  • Feret dimensions

  • Surface roughness indicators

Automated QC / Pass–Fail Tools

Hydro Insight enables definition of tolerance limits for shape, size, or concentration, supporting robust QC processes.

Frequently Asked Questions

Is Hydro Insight compatible with the Malvern Mastersizer 3000?

Yes. Hydro Insight is designed as an accessory for the Malvern Mastersizer 3000 wet dispersion systems and operates in parallel with laser diffraction.

Does Hydro Insight replace laser diffraction?

No. It provides orthogonal image-based data that complements the Mastersizer’s PSD.

What particle sizes can Hydro Insight measure?

The system supports ranges from approximately 1–300 µm (standard) and 10–800 µm (low magnification).

Why combine particle size and particle shape?

Particle shape influences flow, packing, breakage, settling, and performance. Image-based shape metrics help explain PSD changes and improve QC.

Can Hydro Insight detect agglomerates?

Yes. Image-based classification enables reliable differentiation between primary particles and agglomerated structures.

The Hydro Insight is a dynamic imaging accessory that sits alongside the Mastersizer 3000, providing insights that go beyond particle size distribution to particle images and quantitative particle shape data for the Malvern particle size analyzer.

Laser diffraction is a valuable tool for particle size analysis. But to develop truly high-performance products, scientists often need a more comprehensive overview than laser diffraction alone can provide. Specifically, to understand what influences packing, flow, and dissolution rate, researchers need to understand how the combination of particle size and shape affects their materials’ behavior.

The Hydro Insight accessory enables this by combining Vision Analytical’s dynamic imaging expertise with Malvern particle size analyzer. Particles suspended in a flowing stream by the Mastersizer 3000’s dispersion unit flow through the Hydro Insight, and are then photographed and analyzed in real-time for shape.
