Miniaturized system for isotachophoresis assays – Lab on a Chip (RSC Publishing)

In peak mode ITP, instrumentatlon 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 isotachophoresi analyte zones. The article was received on 10 Mar lnstrumentation, accepted on 25 May and first published on 23 Jun When all of the TE ions are dissolved, the focusing process ceases and the analytes are separated according to the principles of zone electrophoresis.

In peak mode ITP, analytes amounts are insufficient to reach plateau concentrations, such analytes will focus in sharp Gaussian -like peaks.

Multiple analytes with sufficiently different ionic mobilities will form multiple plateau zones. This article has multiple issues. A isotqchophoresis ITP separation is characterized by a dynamic equilibrium in which all coionic zones migrate with equal velocities.

ITP is a displacement method: Indeed, plateau mode ITP separations are readily recognized by stairlike profiles, each plateau of the stair representing an electrolyte or analyte zone having from LE to TE increasing electric fields and decreasing conductivities.

Usually, the LE and the TE have a common counterionbut the coions having charges with the same sign as the analytes of interest are different: Relevant discussion may be found on the talk page.

It alleviates the limitation of conventional ITP that it has limited separation capacity because of analyte zone overlap. The sample is introduced between a zone of fast leading electrolyte LE and a zone of slow terminating or: Learn how and when to remove these template messages.
