Chemical species include isotopic composition, electronic or oxidation states and molecular structures. Speciation analysis is the analytical process of identifying and\/or measuring the amounts of one or more individual chemical species in a sample.\u003c\/p\u003e\n\u003cbutton class=\"accordion\"\u003e\u003cstrong\u003eRead more...\u003c\/strong\u003e\u003c\/button\u003e\n\u003cdiv class=\"panel\"\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is speciation important?\u003c\/strong\u003e\u003cbr\u003e Speciation analysis has become important for food, environmental, and pharmaceutical industries, where simply measuring the total amount of an element is insufficient. Identifying the different species and concentrations of those species provides a more informed understanding of the environmental or health related impact associated with a particular sample. The clinical or environmental approach would be very different depending on the concentration of the toxic species. For example, an exposure to toxic inorganic arsenic (arsenite and arsenate) is a much bigger concern than an exposure to the mildly toxic organic arsenic species. In contrast, organic mercury species are more toxic than inorganic mercury species, so an exposure to methylmercury or ethylmercury poses a more severe health risk.\u003c\/p\u003e\n\u003cstrong\u003eHow is speciation analysis performed?\u003c\/strong\u003e\u003cbr\u003e IC-ICP-MS provides a complete inorganic elemental analysis solution for speciation analysis.\u003cbr\u003e\u003cbr\u003e -Metal-free ion chromatography (IC) separates the individual ionic species without contributing trace metal contamination\u003cbr\u003e -Ion Chromatography-Inductively Coupled Plasma Mass Spectrometry (IC-ICP-MS) performs trace elemental detection and quantification\u003cbr\u003e\u003cbr\u003e Metal-free IC (with high resolution ion exchange columns and simple online connectivity) together with high sensitivity ICP-MS and integrated software are a powerful combination for fast and efficient metal speciation.\u003c\/div\u003e\n\u003cbr\u003e\u003cbr\u003e\n\u003cbutton class=\"accordion\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0296\/2155\/1241\/files\/information-btn.png?v=1588344634\" width=\"16px\" height=\"16px\"\u003e \u003cstrong\u003eElement properties\u003c\/strong\u003e\u003c\/button\u003e\n\u003cdiv class=\"panel\"\u003e\n\u003ctable align=\"center\" border=\"0\" cellpadding=\"10\" cellspacing=\"0\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003ctable align=\"right\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0296\/2155\/1241\/files\/cr.gif\" alt=\"Chromium Expanded View\" height=\"182\" width=\"144\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eChromium\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eLocation: \u003c\/b\u003e Group 6, Period 4 \u003cbr\u003e \u003cb\u003eAtomic Weight: \u003c\/b\u003e 51.9961 \u003cbr\u003e \u003cb\u003eCoordination Number: \u003c\/b\u003e 6 \u003cbr\u003e \u003cb\u003eChemical Form in Solution: \u003c\/b\u003e Cr(H\u003csub\u003e2\u003c\/sub\u003eO)\u003csub\u003e6\u003c\/sub\u003e\u003csup\u003e3+\u003c\/sup\u003e \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eStorage \u0026amp; Handling:\u003c\/b\u003e  Keep tightly sealed when not in use.
