ABSTRACT

Depending on the species present, the influence of a metal ion or metal complex within an environment or biological system can be essential or toxic. It is well established that methods exist in the literature on how to differentiate and detect essential and toxic species. Typically, a liquid chromatography (LC) system is coupled to an Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) instrument. In many laboratories, total metals and speciation are typically dedicated to two different ICP-MS instruments. This is because the total metals analysis utilizes a simple autosampler, whereas speciation requires chromatography as the front end of the analysis. Not all laboratories have the space or capital to employee two dedicated ICP-MS instruments, thus we have developed an all-inclusive sample introduction system that can seamlessly switch between total metals and speciation methods. The prepFAST IC combines ESIís prepFAST functions with ion chromatography to allow for inline speciation with autocalibration and autodilution capabilities.
The following presentation will look what is involved in providing an automated platform for the analysis of bromide and bromate, chloride and chlorate, iodide and iodate, and total metals for all EPA recommended elements. This automated platform will consist of the prepFAST IC in combination with an inductively coupled plasma-mass spectrometer (ICP-MS).
