- Provide accurate, concentration-independent results using a patented multiple scatter analysis.
- Feature wide spray plumes with no risk of optical contamination.
- Easily view dynamic spray particle size changes through its unique historical size analysis software.
How it works
The Malvern Panalytical Spraytec uses laser diffraction technology to measure the size of spray droplets and particles. To do this, it measures the intensity of the scattered light when a laser beam penetrates a spray. This data is then analyzed to calculate the size of the droplets that created the scattering pattern.
The Spraytec system consists of the following main elements:
- a transmission modulecontains the collimated laser light source used to illuminate the aerosol during a measurement.
- a receiving modulewhich may contain one of two lenses (300mm or 750mm) that focus the scattered light from the spray onto a series of detectors. These detectors accurately measure the intensity of light scattered by spray droplets over a wide angular range.
- an optical benchwhich ensures that the transmitter and receiver are aligned. The length can be adjusted to suit different applications, with the longest bench being 2.5m.
- About Spraytechwhich monitors the system during the measurement process and analyzes the dispersion data to calculate spray size distributions. The results are displayed as a "size history" trend graph, allowing you to instantly see any change in droplet size over time.

Aerosol Positioning Accessory
Malvern Panalytical's Spraytec aerosol positioning accessory allows users to position aerosol cans or pump sprays relative to the Spraytec laser diffraction measurement zone during particle size and aerosol measurement.
This helps eliminate a major source of variability associated with spray measurements, allowing for reproducible testing of spray products for home and personal use.
air purge accessories
The air purge attachment prevents spray droplets from settling on the Spraytec optics when measuring large or concentrated spray plumes. This enables the routine characterization of products such as paint sprays or agrochemical application systems.
The Spraytec Extraction Accessory provides a means of collecting and capturing droplets and spray particles during spray particle size measurement. This ensures that recirculation of spray particles is reduced during measurements and also helps manage the risks associated with user exposure to spray droplets.
Accessories for inhaler and nebulizer
The Spraytec inhaler and nebulizer accessories offer users the ability to reproducibly measure the particle size distributions of dry powders or droplets produced by metered dose inhalers, dry powder inhalers and nebulizers. Formulations can be quickly checked for the correct dispersion properties, giving researchers the detailed information they need to develop new inhaled drug delivery products.
Nasal Spray Accessory
The nasal spray accessory provides users with the ability to reproducibly measure particle or droplet size distributions generated by nasal drug delivery devices as part of bioequivalence studies or production quality control. Studies can also be conducted to determine how changes in nasal spray device, formulation, or device performance profile may affect the particle size of the spray administered.
wet dispersing accessories
The Spraytec wet dispersing accessory is an economical liquid sample dispersing device designed to measure samples in aqueous or non-aqueous dispersants.

Routine characterization of the atomizer
Measuring the droplet size produced by atomization systems is key to understanding the process and knowing about the environmental impact of spraying, for example in coatings or agrochemical applications.
The Spraytec's robust design, efficient air scavenging and multi-dispersion analysis ensure that measurements at high concentrations can be performed directly in a spray column, providing the real-time data needed to track changes in particle size during atomizer operation.
