How the Sentia™ Analyzer works

Originating from a pedigree of modern point of care (POC) medical devices designed by Universal Biosensors, Sentia uses our expertise in healthcare technology to deliver meaningful, accurate and consistent results in minutes in wine.

The Universal Biosensors core technology consists of a disposable, multi-layer test strip, which incorporates a proprietary electrochemical sensing system using opposing electrodes that rapidly and accurately detects analytes in samples as small as a droplet.

Specialized test strips unique to each test method have a series of widely recognized and researched reagents dried down into a small reaction chamber contained within the strip. Once this test strip is inserted into the device and a single drop of sample is applied, the reagents will dissolve and react with the wine, all whilst the device delivers a voltage to the strip electrodes. Electrons are consequently transferred at the strip electrode surface, and the current generated from this exchange of electrons is measured using electrochemical techniques such as squarewave voltammetry and amperometry. Electrochemical algorithms generated from industry reference methods are then applied to give you a final result within minutes of sample application.
