New Speciation Analysis Capabilities for High Resolution ICP-MS
Oct 31 2007
In recent years there has been increasing interest in the ability to perform measurements of not just the total concentration of elements in samples, but also the relative levels of the different species of elements that are present. This is because each molecular compound or oxidation state of an element exhibits unique properties such as toxicity, reactivity or metabolic pathway in living organisms. An effective analytical approach to enable this type of speciated elemental analysis is by separation, using a chromatographic technique, and detection using the highly sensitive element specific technique of ICP-MS. Separations for volatile species can be performed using gas chromatography (GC), whilst detection with high resolution ICP-MS offers the benefit of increased sensitivity and selectivity. The Thermo Scientific kit enables analysts working in the environmental, clinical and biological markets to detect and quantify the volatile compounds of elements such as sulfur, tin, phosphorous, mercury and bromine, at significantly lower levels than traditional techniques thanks to the solution's high sensitivity and, in some cases, the ability to resolve interfering ions from the mass spectrum.
