LaMotte CHLORINE BLEACH TEST KIT LB-DC - Manual (Page 2)

PRO CE DURE B: 0-1.0% (0-10 ppt)
1.
Use 0.5 mL pipet (0353) to add 0.5 mL of the sample solution to a
test tube (0778). 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 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, % = 0.05 x Number of Drops
Available Chlorine, ppt = 0.5 x Number of Drops
PRO CE DURE C: 0-10% (0-100 ppt)
1.
Use the 0.5 mL pipet (0353) to add 0.5 mL of the sample solution to a
test tube (0778). Dilute to 5 mL line with tap water. Cap and mix.
2. Use the 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).
