Tube for correction (value B)
Almost all colors and turbidities are destroyed under test conditions and do
not interfere. COD resistant colors and turbidities cause deviating results
which cannot be circumvented.
Proceed as described in the test instructions for test 0-31, but add 0.5 mL
distilled water instead of 0.5 mL R3.
Proceed as described in the test instructions for test 0-32, but instead of
0.5 mL R2 add 0.5 mL distilled water.
Proceed as described in the test instructions for test 0-34, but instead of
0.5 mL R2 add 0.5 mL distilled water.
Open DEHA test tube, add 4.0 mL sample, close and mix.
No correction possible.
No correction possible.
Open formaldehyde test tube, add 2.0 mL sample solution, close and mix.
Proceed as described in the test instruction for test 0-42, but instead of
0.2 mL R3 add 0.2 mL distilled water.
Open hardness test tube, add 0.2 mL sample solution, close and mix.
No correction possible.
Open potassium test tube, add 2.0 mL sample solution, close and mix.
Fill empty test tube with 2.0 mL distilled water, 2.0 mL sample solution and
1.0 mL R2, close and mix.
No correction possible.
Proceed as described in the test instruction for test 0-49, but instead of
0.5 mL R3 add 0.5 mL DMSO.
Proceed as described in the test instruction for test 0-50, but instead of
2.0 mL R5 add 2.0 mL distilled water.
Fill empty test tube with 4.0 mL sample and 1.0 mL distilled water, close and
mix (analytical result = A + B).
Proceed as described in the test instruction for test 0-53, but add 0.1 mL
DMSO instead of 0.1 mL R2.
Fill empty test tube with 4.0 mL sample and 0.4 mL distilled water, add 0.2 mL
R2, close and mix.
No correction possible.
The original test already contains a correction.
Fill empty test tube with 4.0 mL sample solution, 0.5 mL distilled water and
0.5 mL R2, close and mix. Add 1 measuring spoon R3, close and shake
vigorously.
Almost all colors and turbidities are destroyed under test conditions and do
not interfere. For samples which are still colored or turbid after decomposition:
Fill empty test tube with 4.0 mL digestion solution.
Fill empty test tube with 1.0 mL distilled water. Add 4.0 mL sample.
