As part of the activities of the BSL, the team are developing a new range of electronic nose/gas analysers based on a range of different in-house and commercial gas sensor technologies. The WOLF (or Warwick OLFaction) electronic noses are the latest of these. Importantly, as these instruments are designed and developed in-house, it allows a high level of freedom allowing the instruments to be tailored to a specific application. Currently there are 4 different series of these electronic noses, some of these are discussed below.
WOLF 4.1 Analyser
The WOLF 4.1 Analyser is a fully integrated electronic nose, containing:
- 4 Series - Desktop electronic nose
- Array of Electrochemical and Optical gas sensors
- Fully integrated control and drive electronics
- Environmental control hardware
- Integrated flow control
- Custom software interface written in National Instrumnts LabVIEW
- Easy to use and simple graphical interface
- Exports to common software analysis platforms
This instrument is already in use for both medical and agricultural applications.
WOLF 3.1 & 3.2 Analysers
The WOLF 3.1 & 3.2 Analysers are small more portable systems that can be taken to site, but are still main powered. The WOLF 3.1 system is fitted with a GC-metal oxide detection system, where pre-seperation occurs in the GC column, followed by chemical interogation using an array of metal oxide sensors. It is fitted with a fully integrated fluidic system, touch screen interface and real-time display.
The WOLF 3.2 is still in development, but uses optical gas sensor apporaches to indentify breath based bio-markers of inflammation. We expect the system to be ready in late 2016.
