Capillary Electrophoresis Instrument

Capillary electrophoresis instruments enable to the separation of charged molecules from each other. Unlike standard SDS-PAGE separation, capillary electrophoresis systems can provide molecule detection after separation through a light source and detector and the system can utilize high voltages without overheating the samples. Applications for capillary electrophoresis instruments include pharmaceutical (i.e. digest analysis of biopharma drugs; peptide mapping), life science (i.e., protein/peptide separation, DNA analysis, and PCR product analysis, chemical (i.e. raw material analysis), forensics (i.e. drug and explosive analysis), environmental (i.e. pesticide analysis) and food/beverage (i.e. as organic acid analysis).

Consideration when purchasing a capillary electrophoresis system:

Capillary electrophoresis provides additional advantages over other analysis methods, like HPLC, GC, SDS-PAGE, which include speed, cost of analysis, and easy method development. First consideration is the type of system required. There are several methods of capillary electroseparation, which include capillary zone electrophoresis, capillary isoelectric focusing, capillary gel electrophoresis, and more. Second consideration is the system’s throughput; how many samples can the instrument run.
