Reaction Principle:

• CH2=CH2 + Pd-Molybdate complex → blue reaction product

Cross Sensitivity:

• Other similar compounds are indicated in addition to ethylene, e.g.:
• 100 ppm butadiene result in a reading of 1 ppm
• 50 ppm butylene result in a reading of 1 ppm
• 5 ppm propylene result in a reading of 1 ppm
• 20 ppm hydrogen sulfide result in a reading of 2 ppm
• 25 ppm CO change the indicating layer to a greyish blue.
