Methods for the determination of nitrite by high-performance liquid chromatography with electrochemical detection.
A review on the use of high-performance liquid chromatography coupled with electrochemical detection (HPLC-ED) for the measurement of nitrite (NO2-) and nitrate (NO3-) is presented. HPLC-ED has been used for the determination of NO2- and NO3- in food, biological and environmental samples. Analysis of the current literature indicates that the measurement of NO2- and NO3- by the HPLC-ED procedure is more sensitive, selective and faster than methods based on UV absorption, photometry, fluorometry or chemiluminescence.
