Tube for correction (value B)
Proceed as described in the test instruction for test 0-61, but instead of
1.0 mL R2 add 1.0 mL NaOH 14 %.
Fill empty test tube with 1.0 mL distilled water. Add 4.0 mL sample.
Fill empty tube with 3.7 mL distilled water and 1 mL sample.
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.
Open nitrate test tube, add 0.2 mL sample and 0.5 mL 2-propanol, close, mix.
Blank value for correction: Open nitrate test tube, add 0.2 mL distilled water
and 0.5 mL 2-propanol, close, mix.
No correction possible.
Fill empty test tube with 4.0 mL sample, add 0.2 mL R2, close, mix.
Open nitrite test tube, add 4.0 mL sample solution, close, mix.
Proceed as described in the test instruction for test 0-70, but instead of
1.0 mL R2 add 1.0 mL distilled water.
Proceed as described in the test instruction for test 0-71, but instead of
1.0 mL R2 add 1.0 mL NaOH 14 %.
Fill empty test tube with 0.5 mL sulfuric acid 50 %, add 1 measuring spoon R2
and 4.0 mL sample solution, close and shake gently. Add 200 μL R3, close,
mix.
Fill empty test tube with 0.5 mL sulfuric acid 50 %, add 1 measuring spoon R2
and 4.0 mL sample solution, close and shake gently. Add 200 μL R3, close,
mix.
Fill empty test tube with 1.0 mL R2 and add 4.0 mL sample solution, close
and mix. Add 1 NANOFIX R2, close and mix.
Proceed as described in the test instruction for test 0-55 / 0-76 / 0-80 / 0-81 /
0-95, but instead of R4 add 0.2 mL distilled water, close, mix.
No correction possible.
Proceed as described in the test instruction for test 0-79, but instead of R3
add 1.0 mL sulfuric acid 20 %, close, mix.
The original tests already contain a correction.
Almost all colors and turbidities are destroyed under test conditions and do
not interfere. For samples which are still colored or turbid after decomposition,
correction values are determined as described above for test 0-64.
Open Residual hardness test tube, add 5.0 mL sample solution, close and
mix.
No correction possible.
Open test tube, add 4.0 mL sample solution and 0.2 mL distilled water, close
and mix.
