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.
Standard version: H2S / SO2 / MM / EM / DMS / DMDS / DES / Total VOC
Upon request: TBM / NPM / MES / 2BM / IBM / NBM / THT / IPM
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.
Standards:
- ISO 19739:2004, DIN 51855/7
- ASTM D 7493-08
- Correlation with EN13 725 / ASTM 679-E04
Features:
- 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
