Abstract

The work which we report on here makes use of a new (patented) technique for measuring the tensile and viscosity properties of any liquid. One modality uses a laser-derived beam of light directed into a drop as it builds up on a drop-head, grows and eventually falls off through gravity. The light is reflected through the drop, and a trace is built up of its intensity over time. The trace has been found to have very good discrimination potential for various classes of liquid. Other sensing modalities can be used, - multiple simultaneous optical and near infrared wavelengths, ultraviolet, ultrasound. In the studies reported on here, we use the ultrasound modality. Further background on this new technology for the fingerprinting of liquid content and composition can be found in McMillan et al.
