DUVAS Technologies

DUVAS is an acronym for Differential UltraViolet Absorption Spectroscopy. It is a highly flexible cost effective family of intelligent portable, mobile and fixed sensors using closed path spectroscopy, capable of detecting multiple pollutants simultaneously at ppb level.

A business located within the Imperial Innovations Incubator combining the best of the collective brainpower of Imperial College with the commercial world.

The result of 10 years R&D at Imperial led by Dr John Hassard, our Chairman

Jointly owned by Imperial Innovations [Aim Listed] and private capital [MDT/Verdetech]

Developing a state-of-the-art AQM system as part of a 3.5M GBP Department of Transport / EPSRC programme www.message-project.org

DUVAS' Mission is to provide:

State of the art, flexible, real time, cost effective and intelligent air quality sensing and monitoring systems for measuring and modelling of ambient air quality...

...that will enable improved decision making to limit the adverse effects of air pollution on human health.

It can provide this through:

Intelligent and comprehensive network/grid or single point sensors

Highly flexible mobile, portable or fixed versions

Wireless enabled for automatic data upload

Comprehensive range of pollutants that can be customised to requirements

Advanced, practical/user friendly, real time analysis, imaging and graphics

Stand alone or part of comprehensive modelling

The ultimate requirement for any sensor network is for the sensors to be fast, accurate and low-cost. DUVAS is closest to satisfying all three conditions:

DUVAS is fast due to the fact that UV light is used to detect a suite of pollutants simultaneously.

DUVAS is accurate due to its robust algorithm developed using high energy physics and remote sensing techniques.

DUVAS is low-cost because instrument capability has been mainly achieved through the software rather than hardware components.

DUVAS is the only product available that can:

Measure a broad range of pollutants;

Measure in ppb;

Be set up as a mobile (for short term measurement) or permanently sited (long term measurement) grid of monitors;

Provide real time data, with measurements taken every few seconds; and

Be networked to cover a wide area.
