Test tube for correction (value B)
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.
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 instructions for test 0-70,
but instead of 1.0 mL R2 add 1.0 mL distilled water.
Proceed as described in the instructions for test 0-71,
but instead of 1.0 mL R2 add 1.0 mL NaOH 14 %.
The original test contains a correction.
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.
Proceed as described in the instructions for test 0-74,
but do not add NANOFIX R2, close, mix.
Proceed as described in the instructions for test 0-55 / 0-76 / 0-80 / 0-81
but instead of R4 add 0.2 mL distilled water, close, mix.
Proceed as described in the instructions for test 0-79,
but instead of R3 add 1.0 mL sulfuric acid 20 %, close, mix.
The original tests 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.
The original test contains a correction.
Open sulfite test tube, add 4.0 mL sample and 0.2 mL distilled water,
close and mix.
Fill empty test tube with 0.2 mL R2, 4.02mL sample solution
and 1.0 mL distilled water, close, mix.
Fill empty test tube with 4.0 mL sample.
The original tests contain a correction.
Fill empty test tube with 4.0 mL sample, add 0.2 mL R2, close and mix.
Proceed as described in the instructions for test 0-97,
add 1.0 mL ethanol instead of R4.
Proceed as described in the instructions for test 0-98,
add 0.5 mL distilled water instead of R3.
Open ethanol test tube, add 4.0 mL R1 and 0.5 mL sample solution (consider
dilution), mix, add 2 drops R3, close and mix.
Open methanol test tube, add 3.0 mL R1 and 1.5 mL sample solution (consid-
er dilution), mix, add 2 drops R3, close and mix.
Fill empty test tube with 4.0 mL sample.
