The Spraytec system with inhalation cell provides for the rapid analysis of inhalers and nebulizers, enabling researchers to understand how particle entrainment and dispersion occurs during device actuation. Particle size in sprays and aerosols is important in defining product delivery and performance in an increasing range of pharmaceutical applications. The Spraytec system uses laser diffraction to measure particle size and it delivers real-time, high-speed measurements that enable the complete characterization of both continuous and pulsed spray events. The unit has an increased data acquisition rate of 10 kHz, which means a 100-microsecond time resolution, allowing extremely accurate analysis of the dynamics of spray atomization and dispersion. Automatic alignment ensures fully optimized system set up. A built-in SOP wizard aids method definition and transferability, and gives single-click operation.
