Use 10 mm square cell adapter.
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
52 Iron-UDV
) from
TESTING MENU
.
4. Scroll to and select
52 Iron-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 the chamber, close the lid and select
SCAN BLANK
.
8. Remove the vial from the Spectro.
9. Use the syringe (1184) to add 3 mL of sample to an *Iron UDV vial (4315).
10. Shake vigorously for 15 seconds.
11. Wait 2 minutes.
12. Invert vial 3 times to mix.
NOTE: If powder residue remains in the bottom of the vial after inverting, or air bubbles
forms, invert vial once more and tap bottom of vial sharply once or twice to dislodge
powder or bubbles. Mix.
13. 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.
NOTES: 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.
UDVs from opened pouches should be used promptly. Store unused vials from opened
pouches in the Foil Storage Bag (9467) to extend the shelf life of the reagent. Generally,
UDVs stored in the bag should be used within 10 days if the humidity is less than 50% and
within 5 days if humidity is greater than 50%. The Foil Storage Bag contains a desiccant
pack with indicator. When the indicator in the window turns from blue to pink, the bag
should be replaced.
