2023年9月19日 · Capillary electrophoresis (CE) is the name of a family of analytical techniques that involve the separation of charged molecules within a narrow capillary tube under the influence of an electric field. What is capillary electrophoresis? - Capillary zone electrophoresis (CZE) - Capillary gel electrophoresis (CGE)
Lab 6: Capillary Electrophoresis - Chemistry LibreTexts
In capillary electrophoresis (CE), the conducting buffer is retained within a capillary tube whose inner diameter is typically 25–75 μm. Samples are introduced into one end of the capillary tube. As the sample migrates through the capillary its components separate and elute from the column at different times.
Capillary Zone Electrophoresis - an overview - ScienceDirect
Capillary Zone Electrophoresis is a method used for determining the pKa of substances like non-steroidal anti-inflammatory drugs with low solubility in water. It involves measuring the mobility of ionic species in electrophoretic buffers at different pH levels. You might find these chapters and articles relevant to this topic.
Capillary Zone Electrophoresis - an overview - ScienceDirect
Capillary zone electrophoresis (CZE) is an efficient, sensitive, and versatile analytical method that is based on combining zone electrophoresis, isoelectric-focusing electrophoresis, and isotachophoresis (see Chapter 8, Chromatography and electrophoresis). CZE systems have been investigated for clinical use for several decades, and there are ...
Capillary Zone Electrophoresis | Science - AAAS
Zone electrophoresis in open tubular capillaries is a useful approach to high-resolution separations of charged substances. Efficient heat transfer from small diameter capillaries permits application of unusually high voltages, which promote more effective separations and increase the speed of analyses.
Capillary Electrophoresis - SpringerLink
2015年1月1日 · The separation modes of capillary electrophoresis (CE) can be classified into three groups: zonal technique, focusing technique, and displacement technique. The zonal techniques consist of capillary zone electrophoresis (CZE), capillary electrochromatography (CEC), and micellar electrokinetic chromatography (MEKC or MECC).
