How it works
Spraytec uses laser diffraction for measuring the size of spray droplets and spray particles. It does this by measuring the intensity of light scattered as a laser beam passes through a spray. This data is analyzed to calculate the size of the droplets that created the scattering pattern. Spraytec is made up of the following main elements:
-
- Transmitter module
-
A transmitter module that contains the collimated laser light source used to illuminate the spray during a measurement.
- Receiver module
-
A receiver module that can hold one of two lenses (300mm or 750mm), which focuses any light scattered by the spray onto a series of detectors. These detectors accurately measure the intensity of light scattered by the spray droplets over a wide range of angles.
- Optical bench
-
An optical bench that ensures the transmitter and receiver are aligned. The length of this can be changed in order to fit with different applications, with the longest bench being 2.5m long.
- Spraytec software
-
The Spraytec software, which controls the system during the measurement process and analyzes the scattering data to calculate spray size distributions. The results are displayed as a ‘size history’ trend plot, allowing any changes in the droplet size over time to be instantly recognized.
Key applications
The flexibility of the Spraytec system makes it ideally suited to applications across a wide range of industries, from fundamental research and development through to product quality control and batch release testing.
It delivers accurate, reproducible spray size analysis in an easy-to- understand format, improving product understanding and control.

- Orally inhaled and nasal drug products
-
Particle size is a key parameter in defining the deposition pattern and bioavailability of drug materials delivered using pump sprays and inhalers to the nasal mucosa and respiratory system. The Spraytec system can chart the changes in size produced during single device actuations, allowing the dynamics of particle dispersion to be identified along with the device reproducibility. Formulations can therefore be rapidly screened for the correct spray properties, reducing development times and improving drug delivery efficacy

- Routine atomizer characterization
-
Measurement of the droplet size produced by atomizer systems is key in promoting process understanding and a knowledge of the environmental impact of spraying, for instance in coatings or agrochemical applications.
The Spraytec’s rugged design, efficient air purge and multiple scattering analysis ensures measurements can be made at high concentrations directly within a spray plume, providing the real-time data required to track changes in particle size during atomizer operation.
Application note: Characterizing spray nozzles for targeted agrochemical application
- Automotive applications
-
The Spraytec’s ability to measure at 10 kHz enables resolution of the fluctuations in droplet size observed during the rapid firing of automotive fuel injector systems. Provision of flexible triggering options ensures each injection event is fully captured. The repeatability of atomization can then be assessed and related to combustion efficiency.
Application note: Characterization of fuel injectors using high speed laser diffraction droplet size measurements
After using and analyzing my spray, I found Spraytec one of the best, most effective and easiest ways to characterize my spray. The Spraytec gives accurate and perfect results for the measurement of droplet size of spray. Moreover, it is very easy and safe to use, the laser is not so strong, so it doesn't effect you at all. Thank you Malvern Panalytical for such a great product.
