INTERFERENCES: a. No interference from copper, iron, or silicate at concentrations many times the concentration of sea water. However, high iron concentrations can cause precipitation and subsequent loss of phosphorus. b. Salt error for samples ranging from 5% to 20% salt content was found to be less than 1%. c. Mercuric chloride, HgCl2,whenusedasthepreservative, interferes when the chloride levels are low (less than 50 mg/L). This interference is overcome by spiking samples with a minimum of 50 mg/L of sodium chloride. Phosphate–LR 2/3 Smart2 TEST PROCEDURES 2.04
PROCEDURE 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 78 Phosphate L) from TESTING MENU. 5. Scroll to and select 78 Phosphate L from menu. 6. Rinse a clean tube (0290) with sample water. Fill to the 10 mL line with sample. 7. Insert tube into chamber, close lid and select SCAN BLANK. 8. Remove tube from colorimeter. Use 1.0 mL pipet (0354) to add 1.0 mL of *Phosphate Acid Reagent (V-6282). Cap and mix. 9. Use the 0.1 g spoon (0699) to add one measure of *Phosphate Reducing Reagent (V-6283). Cap and shake until powder dissolves. Wait 5 minutes for full color development. Solution will turn blue if phosphates are present. 10. At end of 5 minute waiting period, mix, insert tube into chamber, close lid and select SCAN SAMPLE. Record result. 11. Press OFF button to turn colorimeter off or press EXIT buttontoexittoa previous menu or make another menu selection. Smart2 TEST PROCEDURES 2.04 Phosphate–LR 3/3
