| | Acorn™, a New, Simple, Inexpensive Method for Non-Invasive Particle Size Measurement of Suspensions and Droplets | | Authors: | H.S. Dhadwal, B. Mukherjee, D. Fairhurst and S.W. Race | | Affilation: | Dynamic Cosmetics Inc., US | | Pages: | 785 - 788 | | Keywords: | particle size, suspensions, droplets | | Abstract: | Nanoscale particle sizing of colloidal suspensions can be performed with Acorn,™ a new, patented handheld device, that combines remote delivery and detection of laser light, and a direct measurement of particle size, without the use of digital correlators. The former is achieved through a singlemode backscatter fiber optic probe, while the latter is made possible through the implementation of a statistical processing algorithm, which recovers the average particle diameter from the integration time dependent coherence of the scattered intensity. Real-time measurement of the factorial moments, or the coherence of the scattered intensity, is made with a field programmable gate array. A fiber optic backscatter probe permits remote interrogation of samples either by dipping the probe into the solution or by placing the probe outside the container. Acorn™ provides a rapid measurement of the average diameter in the range of 2 to 5000 nm over a broad range of concentrations. | | ISBN: | 0-9767985-0-6 |
