Greetings all,

I have something that has me stumped. What is the best way(s) to determine the concentration of trace secondary and tertiary amides in water? (Concentrations range from 0.1 to 3 ppm). Ideally a spectrophotometric method would be ideal...but I have only seemed to find the bromination method which works for primary amides and hydroxylamine method which isn't sensitive enough. Any help would be much appreciated!!!

Regards,
