Product Overview

The Malvern Spraytec system is specifically designed for spray characterisation. It provides real-time size distribution of spray droplets and aerosols.

The Spraytec uses the technique of laser diffraction. A laser beam passes through the spray which scatters the light creating a scattering pattern. The optics measure the angles and intensity of the scattered light and this is used to calculate the droplet size distribution.

The Spraytec system is made up of a laser module, a detector module and an optical bench to mount and align the laser and detector modules.

The Spraytec software controls the measurement process and analyses the light scattering data to calculate spray size distributions.The results are displayed as a ‘size history’ trend plot showing droplet size changes over time. Measuring parameters can be incorporated into Standard Operating Procedures (SOPs).

Benefits

  • Accurate spray Sizing: over a dynamic range of 0.1 – 2000 microns using just two lens systems.
  • Rapid Measurements: one measurement every 100 microseconds (10kHz) fully captures transient changes in both pulsed and continuous sprays.
  • High Concentration: patented multiple scattering correction ensures spray measurements can be made even at high concentrations.
  • Reproducible simple operation: Measuring parameters can be incorporated into Standard Operating Procedures (SOPs). Prompts ensure correct sample preparation, handling and analysis settings to deliver reliable results.
  • Regulatory compliance: The software provides technical compliance to the requirements of 21 CFR Part 11 and ISO 13320:2009, the international standard for laser diffraction measurements.

Applications

Orally inhaled and nasal drug products
Formulations can be screened rapidly for the desired spray properties reducing development times and improving drug delivery efficacy.

Routine atomizer characterisation
Spraytec’s rugged design and multiple scattering analysis ensures measurements can be made at high concentrations directly within a spray plume. This provides a greater understanding of the environmental impact of spraying in coatings or agrochemical applications.

Automotive applications
Spraytec can be used to measure the fluctuations in droplet size observed during rapid firing of automotive fuel injector systems and provide data related to combustion efficiency.
