Time for Measurement: Approximately 2 minutes / Approximately 4 minutes
Standard Deviation: ± 15 to 20%

Reaction Principle
a) CH2=CH-CN + CrVI → HCN
b) HCN + HgCI2 → HCI
c) HCI + methyl red → red reaction product
   
Cross Sensitivity
The indication is not affected by:
1,000 ppm acetone
20 ppm benzene
1,000 ppm ethyl acetate
1,000 ppm ethanol
10 ppm ethyl benzene
1,000 ppm hexane
100 ppm toluene
Styrene up to 50 ppm does not influence the indication. Butadiene reacts with the oxidation layer; in the presence of butadiene, the acylonitrile indication will be too low (e.g. up to 50 % too low with 400 ppm butadiene).
