MEASUREMENT PROCEDURE · Turn the meter on by pressing ON/OFF. · The meter will first perform an LCD auto diagnostic test by displaying a full set of figures. · Then it will show a scrolling "c 214 Hanna Inst" message. · Wait for a few seconds and the display will show "-0. 0-". · Remove the cap and add the content of one packet of HI 93758-0 Phosphorus Reagent. · Replace the cap tightly and shake gently to mix for 2 minutes until most of the powder is dissolved. Ensure that the vial orientation respect to the holder is the same of the blank. · Press TIMER and the display will show the countdown prior to the measurement. For the program number, see the parameters reference table on page 17 or look at the list printed on the mask of the meter. · When the LCD displays "----", the meter is ready. On the secondary LCD "P1" will appear to inform that the first parameter measurement procedure (Ammonia LR) can be performed. · Press the PROGRAM M and PROGRAM L keys to select the desired parameter. 20 61 Phosphorus, Acid Hydrolyzable · Preheat the Hanna Reactor C 9800 to 150 °C (302°F). Do not use an oven or microwave because leaking samples can generate a corrosive and possibly explosive atmosphere. · Remove the cap from a Reagent Vial. · After the desired program number appears on the secondary display, follow the measurement procedure described in the related chapter. · Select a new parameter measurement procedure by pressing the PROGRAM M and PROGRAM L keys. · Add exactly 5. 0 mL of sample to the vial, while keeping the vial at a 45degree angle. · Replace the cap and mix by inverting the vial a couple of times. Note: in the following measurement sections, a generic "P­ ­" will be placed on the secondary LCD instead of the exact related message (e. g. · Before performing a test read carefully all the instructions related to the selected parameter. · Insert the vial into the reactor and heat it for 30 minutes at 150°C. · At the end of the digestion place the vials carefully in the test tube rack and allow to cool to room temperature. · Select the program number corresponding to Acid Hydrolyzable Phosphorus on the secondary LCD by pressing PROGRAM M and L. · Remove the cap from the vial and add exactly 2. 0 mL of Sodium Hydroxide (NaOH) Solution 1, 20 N, while keeping the vial at a 45-degree angle. · Replace the cap tightly and mix by inverting the vial a couple of times. This is the blank. Phosphorus, Acid Hydrolyzable 60 21 AMMONIA LOW RANGE SPECIFICATIONS Range Resolution Precision Typical EMC Deviation Light Source Method 0. 00 to 3. 00 mg/L (as NH3-N) 0. 01 mg/L ±0. 03 @ 1. 50 mg/L ±0. 01 mg/L Tungsten lamp with narrow band interference filter @ 420 nm Adaptation of the ASTM Manual of Water and Environmental Technology, D1426-92, Nessler method. The reaction between ammonia and reagents causes a yellow tint in the sample.

[. . . ] A single blank vial may be used more than once; the blank vial is stable up to one week if stored in a dark place at room temperature. For most accurate measurement, run a blank for each set of measurements. Do not use an oven or microwave because leaking samples can generate a corrosive and possibly explosive atmosphere. · Remove the cap from two Digestion Vials (red cap vials). green cap · Add the content of one packet of Potassium Persulfate for Total Nitrogen analysis to each vial. red cap · Add the content of one packet of Potassium Persulfate for Total Nitrogen analysis to each vial. · Add exactly 2. 0 mL of sample to one vial (sample vial), and 2. 0 mL of deionized water to the other vial (blank vial), while keeping the vials at a 45-degree angle. · Add exactly 0. 5 mL of sample to one vial (sample vial), and 0. 5 mL of deionized water to the other vial (blank vial), while keeping the vials at a 45-degree angle.
