Cyanide (free) CHEMets® Visual Test Kit - 0-0.1 & 0.1-1 ppm Cyanide CHEMets® Visual Test Kit utilizes a simple yet effective process to accurately measure free cyanide levels. Through the reaction of chlorine and stabilized isonicotinic-barbituric acid, a blue colored complex is formed in direct proportion to the cyanide concentration - providing results in ppm (mg/L) CN-. For total cyanide determination, a preliminary distillation of the sample can be performed.
