The ability to analyse for trace elements is a pre-requisite for metal speciation studies. Many such studies are concerned with environmental samples including solid waste, waste water, drinking water, atmospheric particulates, particulates from emission sou

A variety of ingenious derivatization procedures were devised to improve the gas chromatographic behaviour of thermally labile and/or non-volatile analytes. For example, cationic alkyllead species [R.PbX, R.PbX.; R = CH., C.H.; X = anion] were ethylated, propylated, b

Speciation of Organolead Compounds by GC-AAS,From a chemical viewpoint, three classes of trace element containing species may be distinguished: simple inorganic ions (molecules), organically complexed ions (molecules) and element-organic ions (molecules) containing at least one covalent bond between the trace element and carbon. Each of the ma
