the solution to entirely flow down. Inverse 10 times
-> Zero vial can be stored and used for max. 7 days if stored in the dark
-> Sample needs to be diluted and measurement needs to be repeated if large
quantities of nitrogen free, organic compounds are present, as they may
interfere and reduce the effectiveness of the digestion
-> Bromide >60 mg/l and Chloride >1000 mg/l interfer and change result with
