QUICK AUTHENTICATION OF LIQUIDS

The laboratory has developed a new device for quick and accurate identification and authentication of liquids. A sample of the liquid to analyze is set on a semi conductor plate. A luminous scan of the surface combined with a laser source and a measurement of the current generated through the plate gives a characteristic picture of the liquid.

STAGE OF DEVELOPMENT
A laboratory prototype has been validated :
• Identification of edible oils (800pictures analyzed by treatment of images compared with reference images
• Identification of several alcohol (cognac, armagnac, whiskies)
• Identification of different waters.

INTELLECTUAL PROPERTY
2 Patent pending in France, Europe, Japan and USA
Priority date : December 27, 2012 (FR3000547 and FR3000549)

ADVANTAGES / NOVELTY
• Quick analysis, on and/or off-line
• Product traceability
• Possible miniaturization (portable versions for laboratories and industry)
• Low cost manufacturing
• Multi-parametrical highly-reliable control
• High sensitivity and selectivity
• Small sample volume needed

APPLICATIONS
Biological and non-biological samples :
• Determination of product origins, traceability, fight against counterfeiting (drinks, perfumes, chemicals, ...)
• Rapid on-line and/or off-line control of quality, aging, stability (food, cosmetics, biomedical industries…)
• Security (authentication of dangerous chemical or explosive products, drugs…)

COLLABORATION TYPE
PULSALYS is looking for industrial partners interested in getting a license of these patents and who would like to test the method on their products.
