LaMotte SMART Spectro Spectrophotometer - Manual (Page 128)

PROCEDURE
Use 10 mm square cell adapter.
1. Press and hold
ON button until spectrophotometer turns on.
2. Scroll to and select PROGRAMMED TESTS.
3. Scroll to and select ALL TESTS (or another sequence containing
33 Copper-UDV
) from TESTING MENU.
4. Scroll to and select 33 Copper-UDV from menu.
5. Rinse a clean vial (0156) with sample water.
6. Use the syringe (1184) to add 3 mL of sample to the vial.
7. Insert the vial into chamber, close lid and select SCAN BLANK.
8. Remove vial from Spectro.
9. Use the syringe (1184) to add 3 mL of sample to a Copper UDV vial
(4314).
10. Wait 2 minutes.
11. Invert vial 3 times to mix.
þNOTE: If powder residue remains in the bottom of the vial after
inverting, or air bubbles form, invert once more and tap bottom of vial
sharply once or twice to dislodge powder or bubbles. Mix.
12. Insert tube into chamber, close lid and select SCAN SAMPLE. Record
result.
13. Press
OFF button to turn the spectrophotometer off or press EXIT button
to exit to a previous menu or make another menu selection.
þNOTE: 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 are obtained.
