vigi e-nose

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
