Ion Chromatography (IC) ICP-MS forChromium Speciation in Natural Samples
Trace measurements of the element chromium (Cr) are of interest in a wide range of applications and matrices. In the environment, Cr exists in two different oxidation states, the trivalent Cr(III) cation and hexavalent Cr(VI) anion. In mammals, Cr(III) is an essential element involved in the regulation of glucose; however, the element in its hexavalent form demonstrates mutagenic and carcinogen...
متن کاملSpeciation of arsenic in fish products by LC-ICP/MS
While many elements are considered essential to human health, others can be toxic. However, because the intake, accumulation, transport, storage and interaction of these different metals and metalloids in nature is strongly influenced by their specific elemental form, complete characterization of the element is essential when assessing its benefits and/or risks. This is why, elemental speciatio...
متن کاملSimultaneous separation and determination of Tl(I) and Tl(III) by IC-ICP-OES and IC-ICP-MS
A new hyphenated method was developed for the speciation of Tl. In this method, Tl(III) was complexed with DTPA to form a Tl(III)-DTPA anionic complex. Tl(I) did not form a complex with DTPA. The two species were separated simultaneously by means of ion chromatography using a Dionex cation exchange guard column, CG12A, and 15 mmol/l nitric acid as eluant. When ICP-OES was used as detector the d...
متن کاملChromium Speciation in Water by HPLC/ICP-MS
Chromium exists primarily in two forms: trivalent and hexavalent. Trivalent chromium is present in the cationic form as Cr+3 and is an essential nutrient, but hexavalent chromium is toxic and exists as an anion, either as chromate (CrO4 -2) or dichromate (Cr2O7 -2). Therefore, the analysis of total chromium does not always provide a true indication of the effects of chromium present in a sample...
متن کاملSpeciation analysis of organotin compounds by HPLC-ICP-MS
The toxicity of trace metals in our food, in the products we use and in the environment is an area of increasing concern. As our knowledge has grown, we have come to understand that the toxicity of these elements is highly dependent on the molecular species to which they are chemically bound. Increasingly, regulations are being written to reflect this reality. Monitoring elemental species requi...
