Conor Hogan and LaTrobe U colleagues want to use the audio functions of mobile phones to test for sulphur dioxide in wine. The idea isn’t to ring a chemist with a good nose but to plug wires attached to a chemical test strip into a phone’s audio jack. This is intended to deliver within seconds an accurate reading of sulphites, with the data sent to a cloud-account for analysis.  All but instantaneous testing with on-the-spot outcome is said to be way-better than present slow and unreliable methods. The university is funding the project.
