Allwest Investigations Group is proud to be associated with E-Nose Pty Ltd, a company that designs and builds electronic noses.
These devices monitor, identify and measure smells and other airborne chemicals continuously and importantly, in real-time.
Electronic noses are particularly useful in the following applications:-
- Environmental - reducing the risk and complaints from environment pollution while providing objective measurement and cost savings from odour management.
- Security - monitoring important spaces to protect infrastructure and assets while offering a new technological solution to problems such as graffiti vandalism (see graffit-e-nose)
- Diagnostic, offering new non-invasive and rapid diagnostics, revolutionising the diagnosis of diseases in humans and providing major improvement in flock and herd management.
SECURITY DEVICES
E-Noses can be used in many security and safety contexts, where airborne chemicals are a signal of something requiring urgent attention. Likely scenarios are safety in planes, trains and buses where timely detection of oil fumes or overheating wiring will save lives. In other situations, on production lines or in fume ducts and pipelines, E-Nose sentinels will continuously monitor for leaks or unwanted events, and alert the management.
Graffiti vandalism is costing State and Local Governments many millions of dollars a year. Market studies have shown that people feel unsafe in areas with graffiti, and fewer passengers will use public transport which has graffiti on and inside its vehicles and on stations and infrastructure.
The Mk3 E-Nose has been proved to be an effective graffiti paint detector. In a recent field study with a large rail corporation, the E-Nose distinguished between spray paint and solvent and could detect paint being used at a distance of 45 metres. E-Noses deployed in rail garages will be a new and important deterrent and cost saving measure.
HOW IT WORKS
Our devices consist of arrays of robust and fast acting chemical sensors, supplemented by novel patented electronics and software. Chemicals in the air are detected by the sensor arrays, registering complex odour “images” in real time.
A permanent record is sent to your computer via line or wireless connection, where it is identified, quantified and alarms for abnormal events.
