Introduction

Isotachophoresis (ITP) is one of the electrophoretic techniques useful for the analysis and isolation of ionic substances. The first successful analysis using this method was reported for alkali earth metals and amino acids by Longsworth in 1953. The use of glass capillaries was first reported by Martin and Everaerts in 1967 after the successful separation of metal cations using a glass capillary by Konstantinov and Oshurkova in 1963 and of carboxylic acids using a paper strip by Schumacher and Studer in 1964. Although various names had been used for this method, the name ITP was proposed by Haglund in 1970 and has been widely accepted. It is interesting to note that the root of the present capillary electrophoretic methods is ITP.

An ITP separation is due to the different elec-trophoretic mobilities of the sample components in a similar manner to the other electrophoretic techniques. However, ITP has some characteristic features which distinguish it from the other elec-trophoretic techniques. This article, summarizes the theoretical background of ITP separations and then describes the analytical and preparative equipment used. Finally, separation strategies are given together with typical examples of ITP.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
