Tube for correction (value B)
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, 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 already 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 0.2 mL R3, close, mix.
Fill empty test tube with 0.5 mL R2, add 1,0 mL sample solution, close and mix. Add 1 NANOFIX R3, close and mix.
Using the extraction procedure does not require a correction value.
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.
No correction possible.
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 already contain a correction.
Almost all colors and turbidities are destroyed under test conditions and do not interfere. For samples which are still
b
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 Sulfite test tube, add 4.0 mL sample solution and 0.2 mL distilled water, close and mix.
Fill empty test tube with 0.2 mL R2, 4.0 mL sample solution and 1.0 mL distilled water, close, mix.
Analytical result = A + B
Fill empty test tube with 4.0 mL sample.
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, but instead of 1.0 mL R4 add 1.0 mL ethanol.
Proceed as described in the instructions for test 0-98, but instead of 0.5 mL R3 add 0.5 mL distilled water.
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 (consider dilution), mix, add 2 drops R3, close and
mix.
Fill empty test tube with 4.0 mL sample.
No correction possible.

For tests of this category, the instructions require distilled water
plus reagents as a reagent blank value. Another volumetric flask
25 mL is necessary for the correction value. Distilled water is used
as a blank value for the correction value. For some tests, a special
reagent has to be prepared for correction. If reduced sample vol-
umes are used for a test (dilution due to concentrations which are
too high), the sample volume for determination of the correction
value must be reduced by the same amount.
Preparation for correction (value B)
20 mL sample; 0.2 mL R1, mix; 1 measuring spoon R2, mix; 2 mL R4, mix; fill to 25 mL with distilled water, mix.
20 mL sample; 1 mL R1, mix; fill to 25 mL with distilled water, mix.
The original tests already contain a correction.
