About this document
HPLC Method for Nitrite & Nitrate Analysis by quimicontay is a document available to read on EtoBox.
This document summarizes an HPLC analysis of nitrite and nitrate ions using a mixed-mode column and UV detection. The analysis achieved separation of nitrite and nitrate ions within 7 minutes using a mobile phase of 20% acetonitrile with 70 mM sodium phosphate at pH 3.0. This HPLC method allows for determination of nitrate down to 100 ppb and nitrite down to 200 ppb, providing a simple approach for analyzing these important ions in applications like drinking water quality testing.
