The apparatus consists of a vial with a conical bottom, a grounded platinum electrode, a capillary to inject the aqueous solution, and an adjustable gold anode with a circular bottom that contacts the entire organic phase. EE is also often performed in a capillary electrophoresis capillary. This is referred to as capillary electroextraction, or ...
Capillary electrophoresis aims to separate analytes on the basis of their mass-to-charge ratio by passing a high voltage across ends of a capillary tube, which is filled with the analyte. High-performance liquid chromatography separates analytes by passing them, under high pressure, through a column filled with stationary phase .
Capillary electrophoresis (CE) is a family of electrokinetic separation methods performed in submillimeter diameter capillaries and in micro- and nanofluidic channels.Very often, CE refers to capillary zone electrophoresis (CZE), but other electrophoretic techniques including capillary gel electrophoresis (CGE), capillary isoelectric focusing (CIEF), capillary isotachophoresis and micellar ...
The original interface between capillary zone electrophoresis and mass spectrometry was developed in 1987 [9] by Richard D. Smith and coworkers at Pacific Northwest National Laboratory, and who also later were involved in development of interfaces with other CE variants, including capillary isotachophoresis and capillary isoelectric focusing.
An electropherogram (also called electrophoretogram, sequencing chromatogram, EPG, and e-gram) is a record or chart produced when electrophoresis is used in an analytical technique, primarily in the fields of forensic biology, molecular biology, and biochemistry. [1]
Gel electrophoresis of nucleic acids is an analytical technique to separate DNA or RNA fragments by size and reactivity. Nucleic acid molecules are placed on a gel , where an electric field induces the nucleic acids (which are negatively charged due to their sugar- phosphate backbone) to migrate toward the positively charged anode .
It is a modification of capillary electrophoresis (CE), extending its functionality to neutral analytes, [1] where the samples are separated by differential partitioning between micelles (pseudo-stationary phase) and a surrounding aqueous buffer solution (mobile phase).
More detailed description and several applications of KCE methods (measuring equilibrium and rate constants of molecular interactions, quantitative affinity analysis of proteins, thermochemistry of protein–ligand interactions, selection of aptamers, determination of temperature inside a capillary) can be found in a PDF presentation: KCE is a conceptual platform for kinetic homogeneous ...
