WSURF Case 612
Chromium Speciation Assay
Summary
Speciation of Chromium typically requires either a) separation of Cr(III) and Cr(VI) by ion chromatography followed by inductively coupled plasma mass spectrometry (ICP-MS) or atomic absorption spectroscopy (AAS) analysis of each sample, or b) a difference measurement deriving form colorimetric determination of Cr(IV) and total chromium determination by ICP-MS or AAS. Generally these methods are expensive and are not adaptable to high throughput analysis. Since both the presence and valence state of Chromium are of prominent importance in the evaluation of environmental contamination a rapid, inexpensive, high throughput method for heavy metal analysis is desirable.
Applications & Advantages
- Fast, Inexpensive & Scalable
- Adaptable for analysis of many different metals
- Does not require ion chromatography, AAS or ICP-MS
- Provides for Chromium speciation information
- Quantitative
