I'm running the low range nitrate procedure and I'm not getting any color. What is wrong?
Summary
No color change on nitrate test
Answer
Make sure you are adding both NitraVer6 and NitriVer3 to your sample. The NitraVer6 reduces the nitrate to nitrite, and the NitriVer3 reacts with the nitrite to form a pink color.

Use a nitrate standard solution in place of your sample to make sure you can get accurate results on a solution of known concentration.
