Measuring nitrate/nitrite (NOx) concentrations in water samples v1
[post]
2022
Preserved Fulltext
Colorimetric (i.e., UV-visible spectroscopy) assay for measurements of nitrate/nitrite down to 0.5 µmol•L-1 concentration. Vanadium(III) reduces nitrate to nitrite prior to measurement with traditional Griess reaction. Nitrate and nitrite concentrations can be measured for the same sample. NOTE: This protocol is written for measurement in 96-well plates.
