Malvern Instruments has launched a new generation Spraytec system for particle size analysis of aerosols and sprays. Like its ground-breaking predecessor, the new Spraytec delivers fully automated in situ analysis of high concentration aerosols and sprays from a robust platform, but has a data acquisition rate four time faster, covers more than double the size range, is driven by Standard Operating Procedures that allow single click operation, and has a sleek new look!
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: even the rapid changes in particle size that take place in pulsed spray events such as fuel injector operation can be followed precisely. An extended size range from 0.1 to 2000 microns, using just two lens systems, enables the routine characterization of broad size distributions, with a dynamic range of more than 1000:1 covered by each lens. Malvern's patented multiple scattering analysis additionally ensures accurate measurements at high spray concentrations, where traditional laser diffraction systems would fail.
Spraytec's unique optical design, efficient air purging, and the ability to use a range of optical bench sizes overcome the physical challenges of measuring dense, widely distributed sprays and allow the continuous operation necessary for meaningful measurement and analysis.
