Nitrate Probe Interference

[tastydog]

I need some help understanding what the interfering ions listed for a probe are.

Vernier makes a Nitrate Ion-Selective Electrode that has interference from "-Interfering Ions: ClO4-, I-, ClO3-, CN-, BF4-". I am not a chemist so I do not know what that means to me as far as what I else I may have to compensate for. Do any of those 5 pose issues in a reef tank?

Here is the link to the probe specs.

Thank you for any help.

essentially chloride is the main interfering ion....

Okay. Thank you. Anyone else? - I just want to be sure, I like to have more than one opinion.

What Lou said. :)

heh. okay that is good enough for me.

So, I guess the next question... what is chloride and is there an effective way to measure it? Or is there an easy way to compensate for it without having to test directly for it?

Can anyone help? Chloride or sodium chloride? I really need to figure out what to do here.

Please, anyone.
