Medor Exp ATEX: On-line analysis & monitoring of sulfur compounds in natural gas and gaseous fuels for hazardous area.

Description

The MEDOR® Exp is an industrial gas chromatograph for the analysis and monitoring of sulfur compounds in natural gas and gaseous fuels: H2S, Mercaptans, Sulfides. Two versions exist: ppm range or ppb range.

Technical Specifications

• Speciation and/or total sulfur detection limits: MEDOR® Exp ppm:
  • H2S: 0.1 ppm (0.14 mg/m3)
  MEDOR® Exp ppb:
  • H2S: 5 ppb (7.0 µg/m3) or DMS: 2 ppb (5.1 µg/m3)
• Range adjustable, depending on application: 0/10 or 0/100 or 0/1000 ppm or ppb
• Calculation: total sulfur, total mercaptans...
• Relative Standard Deviation: RSD < 3% on concentration over 48H. RSD < 0.5% on retention time over 48H.
• Cycle Time:
  • H2S 120 s
