Test Procedures
PROCEDURE
Use universal sample holder.
1. Press
ON
button to turn spectrophotometer on.
2. Scroll to and select
PROGRAMMED TESTS
.
3. Scroll to and select
ALL TESTS
(or another sequence containing
2 Aluminum
).
4. Scroll to and select
2 Aluminum
from menu.
5. Rinse a clean Spectro tube (0290) with sample water. Fill to the 10 mL line with
sample.
6. Insert tube into Spectro chamber and select
SCAN BLANK
.
7.
Rinse a clean test tube (0230) with sample water. Fill to the 5 mL line with sample.
8. Remove tube from Spectro. Empty sample from Spectro tube (0290).
9. Add 5 mL sample from test tube (0230) to empty Spectro tube (0290).
10. Use the 0.05 g spoon (0696) to add one measure of *Aluminum Inhibitor Reagent
(7865). Cap and mix to dissolve powder.
11. Use a 1.0 mL pipet (0354) to add 2 mL of *Aluminum Buff er Reagent (7866). Cap and
mix.
12. Use a second 1.0 mL pipet (0354) to add 1 mL of Aluminum Indicator Reagent (7867).
Cap and mix contents. Wait 5 minutes for maximum color development.
13. At end of 5 minute waiting period, mix, insert tube into chamber, close lid and select
SCAN
SAMPLE
. Record result.
14. Press and hold
OFF
button to turn the spectrophotometer off or press
EXIT
button to
exit to a previous menu or make another menu selection.
NOTE: For the 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. Add 5 drops of
Aluminum Complexing Reagent (7868). 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.
