Frequently Asked Questions (FAQs)

What should I do if the reaction zone color on the Nitrate, Quant Test Strip is the same as or darker than the darkest color of the color scale?

If the color of the reaction zone is the same as or darker than the darkest color of the scale, we recommend that you repeat the test using fresh, diluted sample until a result of less than 500 mg/L nitrate ion is observed.

We recommend the following protocol to use the Nitrate, Quant Test Strips:
