Vigi e-nose: Intelligent Online Odor & Pollutant Monitoring

The vigi e-nose is a turnkey solution from Chromatotec for continuous and real-time monitoring of odors, VOCs, and sulfur compounds in industrial and environmental settings. Using autoGC technology, it enables trace-level detection from ppt to ppm, with high repeatability and no drift.

It detects and speciates a wide range of compounds including:

• Sulfur compounds: H₂S, MeSH, EtSH, DMS, DMDS, DES, SO₂, etc.
• VOCs: aldehydes, ketones, BTEX, PAHs
• Amines and ammonia
• Odor units (EN13725, ASTM E679)
• Cl₂, CH₄, CO₂, N₂O and more (on request)

Dynamic odor dispersion modeling is supported with 3D mapping and neighborhood concentration reports. The system includes configurable alarms per compound or group, and can trigger local processes (e.g. deodorization, ventilation) via integrated PLC signals.

Key technical features:

• Detection limits: down to 1 ppb for H₂S, DMS, SO₂; 10 ppt for benzene
• Cycle time: 120s to 30 minutes depending on compound and config
• RSD: <3% concentration, <0.5% retention time over 48h
• Integrated Windows® PC with SSD storage (128 GB)
• Connectivity: Ethernet, Wi-Fi, 4G remote control
• Power: 230V/115V – 100W average consumption
• Optional configurations include:
• Multiplexer for up to 48 sample paths
• GC-MS module for unknown compound ID
• Fully automated calibration with certified internal tubes

Compact formats are available as rack-mount (5U), wall box or full shelter. The system is built for rugged environments (indoor or outdoor) and integrates fully with the vigiOdor cloud platform for real-time map-based monitoring and historical analytics.

Industries served include: refineries, wastewater, composting, rendering, water utilities, petrochemicals.
