How can I determine nitrate in water?

Hello

Trying to find a semi-accurate, cost efficient test for identifying nitrate in water. I've investigated using Litmus paper and investigated using Diphenylamine solution as an indicator for nitrate. Will using Diphenylamine give me a result I can compare? Such as a deeper blue colour indicating an abundance of nitrate in comparison to a lighter one? Maybe I'm missing something here.

Thanks

you can use infrared spectroscopy, or ionic chromatography

I recommend Ion selective electrode method. It’s accurate and there are some electrodes with high sensitivity. Just follow the instructions to get the calibrations. Good thing is that the electrode system is non-destructive for the sample so you can just insert the electrode and get the reading.
