| Application: | This kit is suitable for the detection of chromium in biological, environmental, food, and beverage samples. |
| Biochem/physiol Actions: | In this kit, chromium is determined in a simple, one-step assay in which Cr(VI) forms a specific complex with a chromgenic dye, resulting in a colorimetric (480 nm) product, proportional to the chromium present. Cr(III) can be converted to Cr(VI) with nitric acid/hydrochloric acid, allowing the determination of Cr(III) and/or total chromium [Cr(III) +Cr(VI)]. |
| Features and Benefits: | Compatible with high-throughput handling systems. Can be adapted for use with cuvettes. |
| General description: | Chromium, an essential trace element, is a transition metal that primarily exists in two stable oxidation states, hexavalent [Cr(VI)] and trivalent [Cr(III)]. Chromium is widely used in various industries such as electroplating, leather tanning, chrome paint, dying, hardened steel, ceramic, and glass. Cr(VI) is produced almost exclusively by industrial processes; whereas, in nature chromium primarily exists in its trivalent form. Cr(III) is generally regarded as nontoxic due to its poor absorption. Cr(VI) is considered a pulmonary carcinogen and has tested positive in genotoxicity tests. Cr(VI) is considered a serious pollutant in many water streams due to its carcinogenic potential. In trace amounts, Cr(III) may be required for glucose and lipid metabolism. |
