Spraytec

Wide measuring range without having to change objectivesUp to 10,000 measurements per second and results regardless of concentrationAnalysis of wide aerosols without risk of contaminationFast automatic alignment and optical bench customizable according to your needs

Malvern Panalytical's Spraytec gives you concentration-independent results! It features patented multi-scattering analysis, covering a wide size range (0.1-2000 micrometers), without the need to constantly change objectives.

Contact

Malvern Panalytical Spraytec uses laser diffraction technology to measure the size of spray droplets and spray particles.

The intensity of the scattered light is measured simultaneously as the laser beam passes through the spray. This data is then analysed to calculate the size of the droplets that created the scattering pattern.

The Spraytec system consists of the following components:

A transmitter module with a collimated laser light source

A receiver module with either of the available lenses (300 mm or 750 mm). These are used to focus the light scattered by the spray onto the detectors.

An optical bench ensures that both transmitter and receiver are aligned. The length of the bench can be adjusted to suit different applications. The longest bench is 2.5 m long.

Spraytec software to control the system and analyse the droplet or particle size distribution.

Accessories

Aerosol Positioning Accessory

The accessory enables users to reproducibly position aerosol cans or pump sprays relative to the Spraytec laser diffraction measurement zone during spray droplet and particle size measurements.

This helps to eliminate a significant source of variability associated with spray measurements, enabling the reproducible testing of domestic and personal aerosol products.

Air Purge Accessory

The Air Purge Accessory prevents deposition of spray droplets on the Spraytec optics during the measurement of wide or concentrated spray plumes. This enables the routine characterization of products such as paint sprays or agrochemical application systems. In other words, the accessory prevents the objective lenses from becoming dirty when such samples are being processed.

Extraction Accessory

Provides a means of collecting and capturing spray droplets and particles during measurements. This ensures that spray particle recirculation is reduced during measurements, and also helps manage the risks associated with user exposure to spray droplets.

Inhaler and Nebuliser Accessory

This accessory provides users with the ability to reproducibly measure the droplet or dry powder particle size distributions produced by metered dose inhalers, dry powder inhalers and nebulisers.

Nasal Spray Accessory

This accessory provides users with the ability to repeatably measure the droplet or particle size distributions produced by nasal drug delivery devices.
