Welcome to smalldropsprays.info

This site's purpose is to provide simple, useful information on gathering and analyzing qualitative deposition data for small droplet spectra. You will find enough methodological detail here to design an experiment, execute, and analyze spray deposition including droplet stain diameters as small as 5.3 microns. This is highly useful in understanding high hit number, low percent cover deposition such as on this 2 centimeter square card, magnified and enhanced (below at left): 


Affordable and fast:

If you already have the appropriate scanning equipment and tracers, you can be analyzing data within a couple of hours using these methods. If not, you will find guida
nce here on tracer, collector, and scanner selection, and you should be able to get all these things in a couple of days. Your total hardware investment in collectors, tracer, and high- resolution scanner will be several hundred dollars or less.


Help develop this methodology!

As with all science, evolution and advancement are continuous, and there are often many ways to the solution of a problem. This site includes fundamentals and basic methods. Some of you have advanced well beyond this no doubt. Help evolve this methodology by contributing your insight and experience. Disagree with something? Disputes are welcome as well.

This effort was initially funded by the generous support of following members of the Spray Equipment Research Group- International (SERG-I): The Province of Newfoundland and Labrador, Forest Protection Limited, SOPFIM- Province of Quebec, The Province of Manitoba, and Winfield Solutions, LLC. Additional support for development of this methodology came from the Australia Grape and Wine Authority (AGWA) as part of project UQ1201, 'A generic approach to improving spray coverage', conducted by CPAS, University of Queensland.
