High performance capillary electrophoresis apparatus

High performance capillary electrophoresis instrument High performance capillary electrophoresis is a new type of liquid phase analysis technology with capillary as separation channel and high voltage direct current electric field as driving force. It is another major progress in analytical science after high performance liquid chromatography. It enables analytical science to move from micro rise level to nano rise level, and makes single cell and even single molecule analysis possible, Therefore, the separation and analysis of biological macromolecules such as proteins, which have puzzled us for a long time, have a new idea. The instrument can be used to analyze organic compounds, inorganic ions, neutral molecules, chiral compounds, proteins and peptides, DNA and nucleic acid fragments.
