摘要：

The influence of polyethylene glycol (PEG) on the effective mobilities of alkali and alkaline earth metal cations was investigated. It is shown that appropriate proportions of water and PEG in the leading electrolyte enable a complete separation of this group of cations to be achieved by capillary isotachophoresis (ITP). The high dynamic concentration ranges of the ITP determinations achieved in the operational systems based on water-PEG mixtures are illustrated by practical examples (water samples, urine, aqueous extract of apple flesh). © 1990.
