Reagent A (4841). Cap and mix.
8. Use the 0.15 g spoon (0727) to add one measure of Hydrazine Reagent B Powder
(4842). Cap and shake vigorously for 10 seconds. Wait 2 minutes for maximum color
development. An undissolved portion of Hydrazine Reagent B may remain in bottom of

NOTE: For best possible results, a reagent blank should be determined to account for any
contribution to the test result by the reagent system. To determine the reagent blank,
follow the above test procedure to scan a distilled or deionized water blank. Then follow
the above procedure to perform the test on a distilled or deionized water sample. This test
result is the reagent blank. Subtract the reagent blank from all subsequent test results
of unknown samples. It is necessary to determine the reagent blank only when a new lot
number of reagents is obtained.
