Aqueous samples with some solvent (ethylene carbonate) for Nitrate analysis.
Posted: 05 December 2017 06:15 PM

I see in the methods it says if your samples have some oil in them you can extract it with an organic solvent. So, is it right to assume that a small amount of solvent in an aqueous sample will be okay in the nitrate analysis?

Hello,

Generally speaking, I try to prevent organic solvent, even diluted in the smartchem.
Because cuvettes are in plastic, organic solvent may damage them and create some reading issues.

If it is a water soluble solvent, we will have to test it in several cuvettes to see the impact.
