MSE Analytical Services offers professional Particle Size Analytical Service using HORIBA Partica mini LA-350 Laser Scattering Particle Size Distribution Analyzer or similar instrument. 

* Note: Data analysis service is not included in the list prices.

Highlights: High Quality Data, Competitive Pricing, Technical Support by Scientists.

Sample testing turnaround time: typically 2 weeks after receiving the samples. 

Data delivery: Both test reports in a PDF file and raw data in an MS Excel file will be delivered electronically to the customer. 

Sample Requirements:

Laser particle size analyzer measurement range: 0.1 μm – 1000 μm; supports both dry and wet methods. 

Dry method testing requires 2-3g of sample. The refractive index and density of the sample must be provided.

Wet method testing requires a dispersant (typically deionized water). The refractive index, sample preparation conditions, and other relevant information must be provided. For powder samples, 500 mg is required.

How Laser Diffraction Analysis Works?

Laser diffraction analysis is a technology to quickly measure geometrical dimensions of a particle with size of several nanometers to millimeters by using a laser beam passing through a suspension of particles. It is based on the Fraunhofer diffraction theory, which states that more light is scattered by smaller particles to a larger angle than by larger particles. Sample suspension is placed between the laser light source and detectors. By measuring the scattered light intensity at different locations, it can tell the particles size distribution in the sample.
