The vigi e-nose is an analyzer able to track VOCs, Sulfur compounds and other molecules as ammonia for example. It allows to provide a rich global fingerprint to correlate with human sensory evaluation as dynamic olfactometry as example. It is possible to train the vigi e-nose with human sensory samples to study correlation with ASTM 679-E04 or EN 13725.
As electronic nose, it provides chemical and olfactive fingerprint.
The main differences are that vigi e-nose offers with single instrument :
- Speciation of Sulfurs (H2S, Mercaptans, DMS, DMDS and more coupounds capabilities) thanks to performances and capabilities of MEDOR instrument
- Quantification of tVOC using PID detector embedded on same equipment
- Automatic data validation thanks to internal calibration using permeation tube embeeded on the analyzer
Stand alone solution without any gas cylinders requirements. The use of the Nitrogen generator is highly recommended.
