Low Cross-Sensitivity to Other Gases

The MIDAS S2-I-COS sensor is highly specific. It shows little to no reaction to many other gases found in industrial settings. This means fewer false alarms and more reliable monitoring. Test data shows a “0 ppm” COS reading when exposed to the following gases at the concentrations listed:

• Carbon Monoxide (CO): 3000 ppm applied
• Hydrogen Sulfide (H₂S): 5 ppm applied
• Sulfur Dioxide (SO₂): 75 ppm applied
• Nitrogen Dioxide (NO₂): 50 ppm applied
• Chlorine (Cl₂): 1 ppm applied
• Hydrogen (H₂): 500 ppm applied
• Hydrogen Cyanide (HCN): 100 ppm applied
• Hydrogen Chloride (HCl): 4 ppm applied
• Ethylene (C₂H₄): 10,000 ppm applied
• Nitric Oxide (NO): 50 ppm applied
• iso-Propyl Alcohol (IPA): 2000 ppm applied
• Ethanol: 1000 ppm applied
• FC-3283 (a fluorocarbon): 500 ppm applied
