Industrial electronic nose vigi e-nose

with gas sensor

Overview
The vigi e-nose is an analytical instrument that simultaneously provides chemical and olfactive fingerprinting for volatile organic compounds (VOCs), sulfur compounds and other odorant molecules such as ammonia. It supports correlation with human sensory evaluation and can be trained with sensory samples to study compliance with standards such as ASTM 679‑E04 and EN 13725.

Main features

• Chemical and olfactive fingerprinting in a single instrument
• Speciation of sulfur compounds (H2S, mercaptans, DMS, DMDS, etc.) using MEDOR technology
• TVOC quantification via embedded PID detector
• Automatic data validation and internal calibration with an embedded permeation tube
• Stand-alone operation without gas cylinders; a nitrogen generator is recommended for best performance

Applications and notes
The vigi e-nose is designed for odor monitoring, control and research. It delivers combined chemical and olfactive fingerprints for correlation with sensory panels and dynamic olfactometry. Training with human sensory samples improves alignment with standards (ASTM 679‑E04, EN 13725) and supports environmental monitoring, process control and nuisance odor investigations.
