New generation in situ particle size
analysis
Malvern has launched a new generation Spraytec system for in situ particle size analysis of high concentration aerosols and sprays
Malvern 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 times 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! Particle size in sprays and aerosols is important in defining product performance in a range of applications, from the delivery of pharmaceutical formulations through to the application of coatings and agrochemicals, and the development of fuel injection systems

Spraytec in routine use by Melbourn Scientific
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
However, sprays can be wet, messy and are often transient, making their analysis highly challenging.
The Malvern laser diffraction-based Spraytec system is an established tool for particle size analysis in sprays, delivering real-time, high-speed measurements that enable the complete characterisation of both continuous and pulsed 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 atomisation 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.

Malvern Instruments and Dr David Morton of the Monash Institute of Pharmaceutical Sciences have collaborated in studies on the powder dispersion from a dry powder inhaler, using laser diffraction
An extended size range from 0.1 to 2000 microns, using just two lens systems, enables the routine characterisation of broad size distributions, with a dynamic range of more than 1000:1 covered by each lens.
The Malvern patented multiple scattering analysis additionally ensures accurate measurements at high spray concentrations, where traditional laser diffraction systems would fail.
The Spraytec 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.
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 optimised system set up.
A built-in SOP wizard aids method definition and transferability, and gives single-click operation.
Measurements can be followed in real time.
