Test tube for correction (value B)
Open chloride test tube, add 1.0 mL sample solution
and 1.0 mL distilled water, close, mix.
Open chloride test tube, add 4.0 mL sample solution
and 1.0 mL distilled water, close, mix.
Fill empty test tube with 4.0 mL sample, add 0.2 mL R2, close, mix.
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 instructions for test 0-31,
but add 0.5 mL distilled water instead of 0.5 mL R3.
Proceed as described in the instructions for test 0-32,
but instead of 0.5 mL R2 add 0.5 mL distilled water.
Proceed as described in the 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.
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 instructions for test 0-49,
but add 0.5 mL DMSO instead of 0.5 mL R3.
Proceed as described in the instructions 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 instructions 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 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 sample solution.
Proceed as described in the instructions for test 0-61,
but instead of 1.0 mL R2 add 1.0 mL NaOH 14 %.
Open nitrate test tube, add 0.5 mL sample and 0.5 mL 2-propanol, close, mix.
Blank value for correction:
Open nitrate test tube, add 0.5 mL distilled water and 0.5 mL 2-propanol,
close, mix.
