INFRARED TECHNOLOGY IN BREATH TESTING
Alcohol regulation is different in every European country. So, it became critical to develop a portable technology available to consumers and professionals, to determine the precise amount of alcohol present in any given breath sample.
For the European market, breath alcohol test devices for consumers are mostly based on fuel cells or semiconductor sensors with their intrinsic drawbacks as regard to precision, time of life and necessity to be calibrated and eventually replaced.
Olythe developed for consumer use the first miniature and compact infrared breathalyzer using the same technology commonly used by law enforcement to validate alcohol level concentration.
Breath alcohol test devices for consumers are regulated by the EN16280 standard for the European market. Breathalyzers in order to complain to this standard shall reach defined precision level (below 20pppm) and, for example, being able to operate continuously through 75 measured tests. For a compact device such as the OCIGO, this requires strong performances in measurement precision and energy management.
The accuracy of a NDIR system is mainly due to its path length as described in the Beer-Lambert law, so reducing the overall size the measuring unit from 200mm (evidential breath analyzers) to less than 50mm is a real challenge.
Furthermore, the miniaturization of a NDIR system brings several additional challenges on the measuring cell: low power and high-performance infrared components, precise and stable thermoregulation and robust signal processing.
Until now, the IR Spectroscopy technology and its precision and reliability have been out of reach for people outside out of Law Enforcement, but thanks to Olythe and its 6 years dedicated to R&D, OCIGO, its electronic breathalyzer using IRS technology was born.
Olythe was able to miniaturize this complex technology to fit in your pocket while giving you the precision of the IR Spectroscopy at the fuel-cell technology price.
