“…It can be used to separate thermally labile and non-volatile compounds and is easily interfaced with ICP-MS making it suitable for speciation studies [85]. Unlike GC, derivatization to produce volatile compounds is not required.…”

“…Coupling to HPLC, however, allows for the identification of individual metallic species, which is achieved through the determination of the retention time of species [1]. Further advantages are the allowance of ICP-MS to remove difficult matrices on-line [85]. HPLC-ICP-MS requires samples to be in the liquid form and thus an extraction step is required for non-aqueous samples [7], and so the species of interest should be sufficiently stable so as to avoid species alterations [7; 46], as is the case in all speciation analyses.…”

The ability of plants to hyper-accumulate metals and metalloids from the surrounding environment may pose a significant health risk to both humans and animals since plants form a substantial component of diet. This attribute, however, has also been identified as a useful tool in bioremediation and biomonitoring studies; where assimilated metal(loid)s in plants often correlate to environmental exposure. Since the bioavailability and toxicity of these elements depends upon their chemical form, speciation studies are essential in determining mobility and metabolic pathways. This can be done in a number of ways where sampling, pre-treatment and storage are all important factors affecting speciation. Appropriate analytical techniques for speciation studies can either be direct methods such as XAS, or indirect methods which require species separation prior to analysis. Separation techniques can be in the form of sequential extractions or column separation and analyte detection often utilises instrumentation such as ESI-MS, ICP-MS and ICP-OES.

“…No noticeable differences of the ICP-MS response among the arsenic species could be observed. 3 As reported in this study, ion-pair chromatography, if carefully optimized by the standards, seems to be promising as a suitable choice to separate ions and hydrophilic ionic compounds for the HPLC-ICP-MS analysis. Accumulation of the experimental data will be important for further improvement of the system.…”

The analysis of environmental and biological samples often requires detection at the parts per billion (ppb) level. Plasma source mass spectrometry has potential as a method for the analysis and speciation of trace elements. This is due to the technique's highly selective nature and excellent sensitivity. In comparison to atomic emission detection, detection limits are usually two to three orders of magnitude lower for plasma MS determinations. Interfacing HPLC with plasma MS provides a means of separation that is necessary for speciation. Speciation involves the determination and quantitation of the various chemical forms of a particular element. A host of HPLC-ICP-MS techniques may be used to obtain this information. This brief report will focus on the most recent work in this area, with emphasis on the work done in our laboratory. -Environ Health Perspect 1 03(Suppl 1): 21-23 (1995)
