Hi Edward -

The conditions are at the bottom of the chromatogram.
Perhaps this method was developed to compete with IEX
for nitrates & nitrites in water - I'm not sure.

Thi method uses relatively low UV @ 230.
The 525nm method will be more selective - but requires post
column derivatization. The IC folks will have options for you as
well.

It's up to you to figure out which method provides the best solution for
your needs (and budget) - that's the fun part!
Dear Sir
I've found this method and another one with pphenyl column in your website and I am very interested and I wonder to do some runs at my HPLC, the only problem is dibutylammonium acetate which is difficult to find or extremely expensive. Could be possible to prepare the reagent in other way or buyin it's the only solution?
Thanks in advance.

Andreu Pulido.
