Well, thanks, good to know that, I can prepare such a solution in the lab,
thanks again

It is not that a Nitrate meter/Colorimeter/Spectrophotometer can't
accurately measure
Nitrate, NO3-, they can. It is that they are not set to see Nitrate
correctly in seawater.
If you had a known NO3-- seawater solution std or made a seawater solution
with a known
NO3- concentration, then you could calibrate the meter to that std and it
would be fine.
