Items 114542 and 114773 tolerate high chloride contents samples. The tolerance of COD is low for both. Items 114563, 109713 tolerate high chloride and COD contents but no coloration.
Sample preparation:
Cloudy samples must be filtered before determination.
Determine with the above mentioned test kits.
Nitrate content in mg/l NO3-N = analysis value in mg/l NO3-N
