Description
The NANOCOLOR® Total Chromium Tube Test is for the photometric determination of total chromium.
In acidic medium, chromate ions react with diphenylcarbazide (lyophilised in the tube test) to form a red-violet colored complex. For determination of total chromium, an acid oxidation at 100–120 °C is necessary.
This test is a practical combination of digestion reagent, digestions vessels and pre-dosed tube tests for the determination of total chromium.
Compatible with the following photometers:
