Nitrate+Test+directions

1. Fill sample bottle (0688) with sample water. 2. Fill one test tube (0820) to the 2.5 mL line with water from the sample bottle. 3. Dilute to 5mL line with *Mixed Acid Reagent (V-6278). Cap and mix. Wait 2 minutes. 4. Use the 0.1g spoon (0699) to add one level measure (avoid any excess) of *Nitrate Reducing Reagent (V-6278). Cap and invert gently 60 times in one minute. Wait 10 minutes. 5. Insert test tube into Nitrate-N Comparator (3109). Match sample color to a color standard. Record as ppm Nitrate as Nitrate Nitrogen (NO3-N).


 * To convert to ppm Nitrate (NO3), multiply by 4.4.
