vigi e-nose

Online analysis and monitoring of odorous compounds Sulfur & VOC monitoring

  • Model: vigi e-nose
  • Manufacturer: Chromatotec

The vigi e-nose is the first analyzer able to track VOC & Sulfurs at ppb/ ppt levels. It is more sensitive than human nose. It is composed by one autoGC-ED (MEDOR® Electrochemical wet cell Detector) and PID for VOCs. Zero air generator included in the same box for autonomous operation

On-line applications:

  • Fence line
  • Odor control monitoring
  • Deodorisation process
  • Fugitive emission
  • Process control / CIP
Category:

Principle:

  • Automatic sampling using a loop linked to sampling pump
  • Automatic loop injection on metallic capillary column
  • Isothermal gas chromatograph
  • Detection of all compounds eluting from the column performed by MEDOR® Detector: Electrochemical wet cell Detector which is SSD Sulfur Specific Detector.
  • Signal provided by reaction between the wet cell electrolyte and the sulfur compounds
  • PID dedicated for total VOC measurement.

Key points:

  • Automatic calibration/validation of the data, with embeded permeation tube for sulfurs. No span gases required.
  • Continuous monitoring with automatic online sampling
  • Analytical performances:
    • Specific, linear and very sensitive to sulfur compounds
    • Results validation by automatic standard injection
    • Long term stability using detector installed in reservoir
  • Extremely low maintenance
    • Very long life time detector with electrolyte, up to 10 years
    • Low gas consumption, can be reduced in option
    • More than 10 years data storage
    • No cylinders required thanks to internal calibration tube and gas generators
  • Automatic control with process device
  • Intelligents system with tunable and interactive alarm levels
  • PID detector in addition to MEDOR® detector
  • Powerful VISTACHROM Chromatotec® software:
    • Remote monitoring & injection control
    • Full traceability with on board archiving of results and chromatograms
    • QC Set up and control of threshold alarms
    • Data export by MODBUS / 4-20 mA / 0-10 V
    • Time stamp results

Options:

  • Multiple stream selector (up to 16 streams with one analyser)
  • Portable olfactometer or lab olfactometer (EN 13725)
  • Modeling software with weather station for live odor/chemical impact
  • Complaints management with platform for automatic integration of perception of neighborhood
  • Explosion proof version Exp or Exd for ATEX, IECEx zone 1 and 2 and also for CSA C1D2
  • Calculation modules (Average / Statistics / Odor unit OU e/m3 and more)
  • Automatic data transfert through: Module for 4 outputs 4-20mA / Modbus RTU or TCP IP
  • 24 V DC power supply
  • Electric selection valve to reduce air consumption
  • Wall mounted box
  • Nitrogen generator when standard used for calibration is different from DMS
  • Vigiodor: dispersion modeling software for odor impact
