The University of Auckland requires a Platform for the Characterization of Sprays and Particle Dispersion.

The required instrument must be a device capable of measuring droplet or particle size distribution at the specific location of a spray (droplet or particulate spray). This will give critical information in characterising the spray to understand the resultant functional behaviour of the spray or the product generated from the spray. Some immediate applications, but not limited to the examples given, are the characterisation of spray nozzles in food/fuel applications and inhalers/nebulizers in the medical application.

The instrument is expected to have a droplet/particles resolution between the order of one to hundreds or microns. It is expected to be able to capture and produce droplet/particles size distribution of the spray and will be able to function at the velocity movement of the droplets/particles at least for the applications highlighted above. The instrument must be easy to use in the presence of the spray shielded in away from possible damage from the spray.

The successful Respondent is expect to provide support during the installation of the product, (preferably plug and play). Operation and maintenance training is also expected to be provided by the successful Respondent. The successful Respondent must also provide support by sourcing technical expertise and replacement parts in the event that external maintenance for the instrument is required.

The instrument will allow a more precise design of drugs and food powder, as their dispersion characteristics or their initial size of the droplets from which they are formed will highly determine the functionality of the powder. Our objective is to set up a platform which will allow research groups across the University and the Industry, to accurately characterise in real time, changes in the size distribution and the structure of their particulate or droplet sprays.
