Print PagePhotometric determination with diphenyl-carbazide Reaction basis according to DIN 38 405-D24 In acidic medium, chromate ions react with diphenylcarbazide (lyophilised in the tube test) to form a red-violet coloured complex. Chromium(III) ions are not determined unless they are converted to Cr(VI) by silver-catalysed oxidation with ammonium peroxodisulfate / sulfuric acid.

Compact Multiparameter Photometer PF-12 Plus
For easy and fast measurements
Using NANOCOLOR® bar coded test tubes, the measurement is automatically performed after inserting the cuvette into the cuvette slot. The contact with any dangerous chemicals is avoided because the measurement is performed directly in the test tube. This guarantees maximum safety for the user.
Approved
Reliable and comparable results
The reaction basis of NANOCOLOR® tests is based on international approved standard methods like DIN-, EN-, ISO-, EPA- and APHA.
Precise
Easy handling and highest accuracy
All NANOCOLOR® tests contain accurate predosed reagents, that are directly ready to use and calibrated accessories.
Versatile
The perfect test for every request
For all important parameters in water and wastewater analysis, a large number of tests with different ranges is available.
Unique
No mix up of tests Every
NANOCOLOR® test box is equipped with a colour coded label and can be identified clearly by its colour.
A full overview of all reagents and equipment can be found in the NANOCOLOR Analysis System Brochure.
