Chromium (Cr) occurs at low levels in the environment and is widely used in industrial processes. The element typically exists in two oxidation states, Cr3+ and Cr6+. Cr(III) is an essential trace element, while Cr(VI) is highly toxic and is regulated at low levels in samples including food, drinking water, pharmaceuticals, consumer products and waste electronic materials. The Agilent Cr Speciation Kit delivers fast, routine separation of Cr(III) and Cr(VI) at low levels in drinking water, using LC(IC)-ICP-MS. The Kit provides a proven ion exchange separation with the Agilent 1260 HPLC coupled to the Agilent 7700 ICP-MS. The Cr Speciation Kit is also compatible with the Agilent 1100/1200 LC and 7500 Series ICP-MS systems.
Separation and analysis of both Cr(III) and Cr(VI) at low ng/L levels within 3 minutes.
Reliable peak separation and accurate quantification of Cr species, even in high matrix water samples.
Low level, interference-free Cr analysis is provided by the standard helium (He) mode of the 7700 ICP-MS. Cr background is minimized by the metal-free sample path of the LC bio-compatibility kit or the use of BioInert LC 1260 modules.
Direct control of the Agilent 1260 LC(IC), and integrated, sample analysis and data processing with the ICP-MS MassHunter Workstation and Plasma Chromatographic software.
Complete, proven speciation solution includes Handbook, LC-ICP-MS Connection Kit and column for Cr speciation in water.
The Cr Speciation Kit can be used for separation and quantification of both Cr(III) and Cr(VI), or for ultra-low level analysis of Cr(VI) alone.
