Multiple analytes with sufficiently different ionic mobilities will form multiple plateau zones.

This may take some time to load. In peak mode ITP, analytes amounts are insufficient to reach plateau concentrations, such analytes will focus in sharp Gaussian -like peaks.

Jump to site search. The analytes of interest have intermediate ionic mobility. For reproduction of material from NJC: Isotachophoresis ITP is a technique in analytical chemistry used for selective separation and concentration of ionic analytes.

Single-electrolyte isotachophoresis using a nanochannel-induced depletion zone.

It alleviates the limitation of conventional ITP that it has limited separation capacity because of analyte zone overlap. ITP is a displacement method: Details about the sub-components of the hand-held instrument PDF K.

Please help to improve this article by introducing more precise citations. Jump to main content.

In peak mode ITP, analyte peaks will strongly overlap, unless so-called spacer compounds are added with intermediate ionic mobilities between those of the analytes; such spacer compounds are able to segregate adjacent analyte zones.

If present in sufficient amounts, focusing analyte ions can displace all electrolyte coions, reaching a plateau concentration.
