Still Spraying After all These Years

It is now 30 years since the launch of the 2600, Malvern Instruments’ first laser diffraction particle size analyser capable of routine, rapid spray droplet size measurements. To celebrate, Malvern wants

to contact anyone still successfully using the 2600 for spray analysis and is inviting visitors to ILASS Europe to bring a photo of their 2600 in action to the Malvern booth. Anyone who does so will be entered into a prize draw to win an iPod Nano.

Bringing spray measurement right up to date, Dr Anne Virden from Malvern Instruments will present a paper at the conference focusing on ‘The effect of viscosity, pump mechanism and orifice diameter on the droplet size of a nasal spray’. Dr Virden’s paper describes work undertaken using Malvern’s latest Spraytec system, and exemplifies just one of its many current applications in the pharmaceutical sector.

In the course of more than a quarter of a century in spray research, Malvern has pioneered developments in both the technology of spray measurement using laser diffraction and its applications. Today this expertise is embodied in the Spraytec, delivering a data acquisition rate of up to 10kHz, a very broad dynamic range (0.1 to 2000 microns) and a patented multiple scattering algorithm for measurement at high concentrations. With easy instrument configuration and a wide optical working range making the spray system characterisation straightforward, integral software provides effective data analysis, making it easier to detect and understand the source of any variability in atomisation performance. Fuel injectors, agrochemical nozzles, inhaled pharmaceuticals and coating systems are just a few of the

many applications for which Spraytec offers a unique solution.
