Spray Particle Size Analyzers

M-Kube Enterprise LLc supplies advanced spray particle size analyzers for measuring and evaluating droplets, aerosols, mists, and atomized liquids. Designed for research, product development, quality control, and industrial testing, these systems support applications across pharmaceutical, chemical, agricultural, combustion, materials science, and academic research environments throughout the United States.

Using laser-based measurement technology, a laser spray particle size analyzer determines droplet and particle size distributions directly within the spray field. This non-contact approach allows users to evaluate spray behavior without collecting droplets on a substrate or significantly disturbing the spray pattern.

M-Kube Enterprise offers compact bench top spray particle size analyzer configurations for smaller spray devices as well as split-type systems for large nozzles, industrial sprays, and research setups requiring adjustable measurement distances.

Our current spray analyzer range includes Model 311, Model 311PRO, Model 319A, Model 319B, and Model 319C.

How Does a Spray Particle Size Analyzer Work?

A spray particle size analyzer measures the size distribution of droplets or particles generated by a nozzle, atomizer, nebulizer, aerosol device, or other spray-producing system.

As the spray passes through a laser beam, individual droplets scatter the light. The analyzer detects the intensity and angular distribution of this scattered light and applies the appropriate scattering or diffraction model to calculate the droplet-size distribution.

Because measurements are performed optically, the system can characterize a spray without requiring physical collection of the droplets.

A spray droplet size measurement system can provide valuable information including:

• Droplet-size distribution
• Fine-droplet fraction
• Coarse-droplet fraction
• D10, D50, and D90
• Spray uniformity
• Atomization behavior
• Nozzle performance
• Effects of operating pressure
• Effects of formulation changes
• Effects of nozzle design
• Changes in spray characteristics during product development

The systems are suitable for liquid sprays, mists, and aerosol-type measurements, with open measurement areas that can be configured around the required test arrangement.

Key Features of Spray Particle Size Analyzers

Non-Contact Spray Droplet Measurement

Spray particle size measurements can be performed without physically collecting droplets or placing sampling equipment directly within the spray.

This approach is particularly valuable when engineers and researchers need to evaluate a spray while maintaining conditions that closely represent the actual operation of the nozzle, atomizer, or spray device.

The Model 319 series uses a split-type optical configuration, providing additional flexibility when integrating the analyzer into industrial or research test setups.

Open and Adjustable Measurement Area

The Model 319 series provides an open measurement region, allowing the optical transmitter and receiver to be positioned around the spray source.

The published adjustable testing area is 0.1–10 m, making these systems suitable for different spray distances, nozzle arrangements, and experimental configurations.

Applications can include:

• Spray dispersion measurements at different distances
• Nozzle performance evaluation
• Spray pattern development
• Atomization studies
• Large industrial spray systems
• Research-scale combustion and propulsion systems

Automatic Optical Alignment

M-Kube spray analyzers incorporate automatic optical-path alignment to simplify instrument setup and help maintain consistent measurement conditions.

Automatic alignment is particularly useful with open or split optical systems where the transmitter and receiver assemblies are positioned independently around the spray.

Wide Particle Size Measurement Capability

The Model 319 family provides several measurement-range options extending from 1 µm up to 2000 µm, depending on the selected model.

The lower measurement limit can be extended to 0.1 µm.

This allows users to select an industrial spray particle size analyzer according to the anticipated droplet-size distribution and application instead of relying on one measurement configuration for every type of spray.

Rapid Data Acquisition

The Model 319 series provides a specified data acquisition rate of ≥2 kHz, allowing rapidly changing spray conditions to be evaluated.

This capability can be useful for:

• Pulsed sprays
• Changing nozzle conditions
• Transient atomization
• Spray-pressure studies
• Dynamic spray research

Optical Lens Protection

Spray and aerosol testing can expose optical components to droplets, mist, and other airborne material.

M-Kube spray systems incorporate airflow/gas protection around the optical components to help reduce droplet contamination of the lens during testing.

Multiple Particle Distribution Models

The analyzer software supports several methods for evaluating and presenting particle and droplet size distributions, including:

• Free distribution
• R-R distribution
• Log-normal distribution
• Volume distribution
• Number distribution
• Statistical comparison
• User-defined analysis parameters

These options allow users to configure analysis and reporting according to different testing procedures, research objectives, and industry requirements.
