If the correction factor is so low in the same matrix with several
samples that it is negligible for the measurement problem at hand,
the determination can be omitted. However, this only results from
practical testing and is not evident beforehand!
When measuring the correction value, a clean, empty tube filled
with distilled water is used as the zero value (exception: tests
0-59 / 0-64 / 0-65 / 0-66).
tube tests

Tube for correction (value B)
Proceed as described in the instructions for test 0-01, but do not add NANOFIX R2. Seal, mix.
Proceed as described in the instructions for test 0-02 / 0-03 / 0-04 / 0-05 / 0-06 / 0-08 but do not add NANOFIX R2, close,
mix.
Almost all colors and turbidities are destroyed under test conditions and do not interfere. Resistant colors and turbidities
cause deviating results which cannot be circumvented.
The original test already contains a correction.
Fill empty test tube with 4.0 mL sample, add 0.2 mL R2, close and mix.
Open carbonate hardness test tube, add 4.0 mL sample solution, close, mix and adjust to zero (value B). Open test tube
again, add NANOFIX R2, close and shake well. Measure after 2 min (analytical result = A – B).
Fill empty test tube with 4.0 mL sample for each test.
Fill empty test tube with 4.0 mL sample for each test.
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. 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.
Proceed as described in the instructions 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 instructions for test 0-49, but instead of 0.5 mL R3 add 0.5 mL DMSO.
Proceed as described in the instructions for test 0-50, but instead of 2.0 mL R5 add 2 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, instead of 0.1 mL R2 add 0.1 mL DMSO.
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 of the digested solution.
Fill empty test tube with 4.0 mL sample solution and 1.0 mL distilled water, close, mix.
Proceed as described in the instructions for test 0-61, but instead of 1.0 mL R2 add 1.0 mL NaOH 14 %.
Fill empty test tube with 4.0 mL sample solution and 1.0 mL distilled water, close, mix.
Fill empty test tube with 3.7 mL sample solution and 1.0 mL distilled water, close, mix.
