Cell accessory for spray system

Malvern Instruments' new generation Spraytec system will be on display at the forthcoming Drug Delivery to the Lungs conference, which will take place from the 7 - 9 December 2005.

Malvern Instruments' new generation Spraytec system will be on display at the forthcoming Drug Delivery to the Lungs conference, which will take place from the 7 - 9 December 2005 at the Edinburgh International Conference Centre in Scotland.

This will be the first exhibition at which the new Inhalation Cell accessory for the system will be shown.

The 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.

Malvern's Spraytec system uses laser diffraction to measure particle size and is widely used in the pharmaceutical industry for the analysis of inhalers, sprays and aerosols.

It delivers real-time, high-speed measurements that enable the complete characterization of both continuous and pulsed spray events.

The new Spraytec 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.

The robustness and simple operation of the Spraytec are important factors in its continued success and both are evident in the new system, from the design of the optical bench through to its software implementation.

Automatic alignment ensures fully optimized system set up.

A built-in SOP wizard aids method definition and transferability, and gives single-click operation.

For use in regulated environments, full lifecycle documentation, following GAMP guidelines, provides complete design traceability; IQ/OQ documentation is provided for validation plans; and software provides technical compliance with the requirements of 21 CFR Part 11.
