DETERMINATION OF HIGH-RANGE SIMPLIFIED TKN WITH TNTPLUS
WebbWe run TKN by EPA 351.2. We use a discreet analyzer so the method is modified a bit. If you were switching to the Hach method you can still follow the same QC as the EPA method just using the Hach tubes/reagents. Double check with your quality department if your regulatory agency accepts the Hach test as equivalent to accepted methods. WebbSimplified TKN (s-TKN) is method accepted for compliance reporting in many states. Please check with local regulators for acceptance in your state. Hach Method 10242 is compliant for EPA wastewater reporting and gives three results for each test - Total Nitrogen, combined nitrate and nitrite, as well as TKN. Unique vial reagent system … WebbS-TKN™ EQUATION • TKN is a component of total nitrogen, and is the sum of organic nitrogen and ammonia. Therefore, the TKN equation may be re-written as: - -Total Nitrogen = NH 3 + Org-N + NO 3 + NO 2 • The s-TKN method is based on this nitrogen relationship. s-TKN is defined as the difference between the concentration of TN and Nitrate ... popovo weather
