*WARNING: Reagents marked with an * are considered to be potential health hazards. Search for the four digit reagent code number listed on the reagent label, in the contents

list or in the test procedures. Omit any letter that follows or precedes the four digit code number. For example, if the code is 4450WT-H, search 4450. To obtain a printed copy, contact LaMotte by email, phone or fax.

To order individual reagents or test kit components, use the specied code number.

PROCEDURE A: 0-0.1% (0-1000 ppm)

1. Fill test tube (0608) to 5 mL line with sample solution.

2. Use a pipet (0369) to add 0.5 mL of Hypochlorite Reagent B (7940). Swirl to mix.

3. Use the second pipet (0369) to add 0.5 mL of *Hypochlorite Reagent A (7939PS). Swirl to mix. Sample will turn brown.

4. Fill glass pipet (0342) with Hypochlorite Reagent C (7941PS). Hold pipet vertically. While gently swirling tube, add Hypochlorite Reagent C, one drop at a time, until brown color disappears. Count the number of drops added.

5. Calculate result:

Available Chlorine, % = 0.005 x Number of Drops

Available Chlorine, ppm = 50 x Number of Drops

PROCEDURE B: 0-1.0% (0-10 ppt)

1. Use a 0.5 mL pipet (0353) to add 0.5 mL of the sample solution to a test tube (0608). Dilute to 5 mL line with tap water. Cap and mix.

2. Use a pipet (0369) to add 0.5 mL of Hypochlorite Reagent B (7940). Swirl to mix.

3. Use the second pipet (0369) to add 0.5 mL of *Hypochlorite Reagent A (7939PS). Swirl to mix. Sample will turn brown.

5. Calculate result:

Available Chlorine, % = 0.05 x Number of Drops Available Chlorine, ppt = 0.5 x Number of Drops

PROCEDURE C: 0-10% (0-100 ppt)

1. Use a 0.5 mL pipet (0353) to add 0.5 mL of the sample solution to a test tube (0608). Dilute to 5 mL line with tap water. Cap and mix. Rinse the pipet.

2. Use the same 0.5 mL pipet to transfer 0.5 mL of the diluted sample to second test tube (0778). Dilute to 5 mL line with tap water. Cap and mix.

3. Use a pipet (0369) to add 0.5 mL of Hypochlorite Reagent B (7940). Swirl to mix.

4. Use the second pipet (0369) to add 0.5 mL of *Hypochlorite Reagent A (7939PS). Swirl to mix. Sample will turn brown.

5. Fill glass pipet (0342) with Hypochlorite Reagent C (7941PS). Hold pipet vertically. While gently swirling tube, add Hypochlorite Reagent C, one drop at a time, until brown color disappears. Count the number of drops added.

6. Calculate result:

Available Chlorine, % = 0.5 x Number of Drops
