We suggest the possibility of practical utilization of a new electrolyte system for fast preparative focusing in wide pH range based on bidirectional isotachophoresis. The focusing occurs on nonwoven fabric strip positioned in an open horizontal V-shaped trough. It is based on bidirectional ITP with multiple counter ions and spacers created from commercially available simple buffers. Milk spiked with ampicillin was used as a sample and high performance liquid chromatography was as a second dimension for analysis of fast preparative focusing fractions. Speed, easy fraction handling, and possibility of pre-concentration of analytes from a raw sample are the benefits of this technique.
