Capillary isotachophoresis
WebCapillary electrophoresis (CE) encompasses a family of related separation techniques (isotachophoresis, isoelectric focusing, affinity electrophoresis, electrokinetic, chromatography, and electrochromatography) that use narrow-bore fused-silica capillaries with an inner diameter of 25–75 μm, to separate a complex array of large and small ... A popular form of ITP is transient ITP (tITP). It alleviates the limitation of conventional ITP that it has limited separation capacity because of analyte zone overlap. In transient ITP, analytes are first concentrated by ITP, and then can be baseline separated by zone electrophoresis. Transient ITP is usually accomplished by dissolving the sample in the TE and sandwiching the sample/TE plug between LE zones - or vice versa: a sample/LE plug can also be sandwiched between TE …

WebSep 1, 2000 · We have developed a novel analytical method for serum lipoproteins using a commercially available capillary electrophoresis apparatus, BioFocus 3000 (Bio-Rad Laboratories Co Ltd, USA). The analytical principle is isotachophoresis (ITP), using a carrier ampholyte, BioLyte 7/9, as a spacer ion. Webcapillary isotachophoresis varies according to the conditions and nature of the sample from 5 to 30 minutes. This technique is characterized by high accuracy (2% rel.) and …

The mobility is independent of voltage and capillary length but is highly dependent on the buffer type and pH as well as temperature. 3) Two capillary lengths are important: the length to the detector, Ld, and the total length, Lt. While the measurable separation occurs in the capillary segment, Ld, the field strength is
WebJul 5, 2011 · We present a novel technique for coupling isotachophoretic preconcentration and electrophoretic separation using bidirectional isotachophoresis (ITP). Bidirectional ITP simultaneously sets up sharp ITP interfaces between relatively high- and low-mobility cations and high- and low-mobility anions.
