Description

• The sample is ready for immediate analysis.
• If a solution is not to be analyzed within two days after opening, preserve a sample aliquot with 0.2 mL of concentrated sulfuric acid per 100 mL of sample (pH<2) and store at 4 ℃ until just before analysis.
• Analyze the preserved sample as soon as possible within the maximum 28-day holding time.

NOTE: The acidification of the sample could result in the oxidation of Nitrite, so it is recommended that 100 mL is separated and not preserved if unable to test for nitrite immediately.
