*WARNING: Reagents marked with an * are considered to be potential health hazards. To view or print a Material Safety Data Sheet (MSDS) for these reagents go to www.lamotte.com. To obtain a printed copy, contact LaMotte by e-mail, phone or fax.

To individual reagents or test kit components, use the specified code numbers.

NOTE: The sampling period specified in the instructions corresponds to concentrations which may be encountered in ambient air conditions. High concentrations of pollutants in the atmosphere will require shorter sampling periods, while low concentrations will require longer sampling periods.

USE OF THE OCTET COM PARA TOR

The Octet Comparator contains eight permanent color standards. A test sample is inserted into the openings in the top of the comparator. The sample can then be compared to four color standards at once, and the value read off the comparator. For optimum color comparison, the comparator should be positioned between the operator and a light source, so that the light enters through the special light-diffusing screen in the back of the comparator. Avoid viewing the comparator against direct sunlight or an irregularly lighted background.

PRO CE DURE

1. Pour 10 mL of *Ammonia Nitrogen Absorbing Solution (7737) into impinging apparatus. Connect impinging apparatus to intake of air sampling pump.

NOTE: Make sure the long tube is immersed in the absorbing solution.

2. Set flowmeter to sample at a rate of 1.0 Lpm for 10 minutes or until a measurable amount of ammonia is absorbed.

3. At the end of the sampling period, add contents of impinger to the 5 mL line of test tube (0230).

4. Add 2 drops of Ammonia Nitrogen Reagent #1 (4797WT). Cap and mix.

5. Add 8 drops of *Ammonia Nitrogen Reagent #2 (4798WT). Cap and mix. Solution will turn yellow to brown color if ammonia is present.

6. Place test tube into Ammonia In Air Comparator (7736). Match sample color to index of color standards. Note the index number which gives the proper color match. Record results as ppm Ammonia Nitrogen.

NOTE: To convert ammonia nitrogen to ammonia, multiply chart value by 1.2. Record as ppm Ammonia.
