Particle Size Analyzer

Particle Size Analyzers are advanced scientific instruments used to measure the size distribution of particles in a sample. They are widely used in research, quality control, and process monitoring across industries such as pharmaceuticals, food, chemicals, and materials science.

Key Details:

Category: Analytical Instrument / Particle Measurement

Description:
Methodology: These analyzers primarily use Laser Diffraction (Mie and Fraunhofer theory) to measure the angular intensity of light scattered by particles. Small particles scatter light at high angles, whereas larger particles scatter light at low angles.

Instrument Examples:
CILAS (e.g., 1190/990): Multi-laser systems (often 3 lasers) covering a wide measurement range (0.04 µm to 2.5 mm) with software- controlled switching between wet and dry dispersion. Some models include image analysis for particle shape characterization.
Malvern (e.g., Mastersizer 3000): Industry-standard, high-speed analyzers for dry powders, suspensions, and emulsions, covering ranges from 10 nm to 3.5 mm with fast, robust measurement capability.

Sample Handling: Includes wet dispersion for liquids/slurries and dry powder modules for solid samples.

Materials Analyzed:

• Titanium Dioxide
• Silica
• Various powders, suspensions, and emulsions

Common Uses / Applications:

• Pharmaceuticals: Ensuring drug dissolution rates, bioavailability, and stability.
• Materials Science: Characterizing cements, ceramics, metals, and paints.
• Food and Beverage: Controlling particle size in ingredients like coffee, chocolate, or flour to affect texture and taste.
• Environmental Monitoring: Assessing particulate pollution in air and water.
• Chemical Manufacturing: Optimizing emulsions and dry powders.

Key Features:

• Measurement Range: Sub-micron to millimeter scale (e.g., 0.04 µm to 2.5 mm for CILAS 1190).
• Speed: Rapid analysis with results often available in less than 10 minutes.
• Compliance: ISO 13320 compliant for laser diffraction particle sizing.
