Spray analysis seminar was cooperative
effort
One-day seminar by Malvern Instruments, Copley Scientific, and Melbourn Scientific presented delegates with an opportunity to learn about different techniques for pharmaceutical spray analysis
Combining their expertise in laser diffraction, cascade impaction, and the practicalities of pharmaceutical analysis, the three companies says they were able to deliver an extremely useful seminar, successfully complementing theory with practical demonstrations Spray analysis is critical for the development and QC of inhalation devices, including nasal sprays, nebulisers, and metered dose and dry powder inhalers

Melbourn Scientific has become the first CRO in the UK to routinely use the Malvern Instruments Spraytec particle size analyser to support the development of inhaler, nebuliser and nasal spray systems
Reviewing the day, Paul Kippax, product manager diffraction products for Malvern Instruments, said: "We see laser diffraction and cascade impaction as complementary techniques for the sector, a view highlighted by our decision to host this event.
"Malvern, Copley, and Melbourn all have different experiences to contribute and this gave the event broad appeal.
"Feedback has been extremely positive and we plan to develop and repeat the seminar next year".
The seminar began with a presentation from each of the companies.
These covered the topics of regulatory requirements for product testing, the application of laser diffraction in product development, and the practice and pitfalls of regulatory product testing.
Later sessions demonstrating the use of laser diffraction for nebuliser and nasal spray characterisation, and the set up and use of the Next Generation Impactor (NGI), furnished participants with practical tips for effective and efficient analysis.
Laser diffraction provides real-time particle size measurement during a spray event giving insight into the dynamics of spray formation.
Cascade impaction on the other hand uniquely allows determination of the aerodynamic particle size distribution of the active ingredient within a formulation.
Both techniques are valuable to the pharmaceutical industry, which has significant interest in the development of inhalation products. Request a free brochure from Malvern Instruments ...
