INTERFERENCES: Nitrite interferes at all levels. Strong oxidizing and reducing substances interfere. Low results might be obtained for samples that contain high concentrations of iron and copper. Nitrate-Nitrogen–LR 2/3 Smart2 TEST PROCEDURES 1.07
PROCEDURE NOTE: Place Dispenser Cap (0692) on *Mixed Acid Reagent (V-6278). Save this cap for refill reagents. 1. Press and hold ON button until colorimeter turns on. 2. Press ENTER to start. 3. Press ENTER to select TESTING MENU. 4. Select ALL TESTS (or another sequence containing 64 Nitrate-N LR)fromTESTING MENU. 5. Scroll to and select 64 Nitrate-N LR from menu. 6. Rinse a clean tube (0290) with sample water. Fill to 10 mL line with sample. 7. Insert tube into chamber, close lid and select SCAN BLANK. 8. Remove tube from colorimeter and pour off 5 mL into graduated cylinder or similar. Discard the remaining sample. 9. Pour the 5mL sample from a graduated cylinder or similar into the tube. Use the graduated cylinder or similar to measure 5 mL of *Mixed Acid Reagent (V-6278) and add to tube. Cap and mix. Wait 2 minutes before proceeding to Step 10. 10. Use the 0.1 g spoon (0699) to add two measures of *Nitrate Reducing Reagent (V-6279). Cap. 11. Hold tube by index finger and thumb and mix by inverting approximately 50-60 times a minute for four minutes. Wait 10 minutes for maximum color development. NOTE: At end of waiting period an undissolved portion of Nitrate Reducing Reagent may remain in bottom of the tube without affecting results. 12. At the end of the 10 minute waiting period, mix, insert tube into chamber, close lid and select SCAN SAMPLE. Record result. 13. Press OFF button to turn colorimeter off or press EXIT buttontoexittoa previous menu or make another menu selection. NOTE: For best possible results, a reagent blank should be determined to account for any contribution to the test result by the reagent system. To determine the reagent blank, follow the above test procedure to scan a distilled or deionized water blank. Then follow the above procedure to perform the test on a distilled or deionized water sample. This test result is the reagent blank. Subtract the reagent blank from all subsequent test results of unknown samples. It is necessary to determine the reagent blank only when a new lot number of reagents are obtained. To convert Nitrate Nitrogen (NO 3 –N) results to ppm Nitrate (NO 3 ), multiply by 4.4. Smart2 TEST PROCEDURES 1.07 Nitrate-Nitrogen–LR 3/3
