The goods In addition to its CE system, Agilent sells the 2100 BioAnalyzers, lab-on-a-chip devices that use electrophoretic separations. The BioAnalyzer is more of an appliance than an analytical instrument, with each chip doing one thing such as RNA, DNA, or protein analysis. With these chips, no method development occurs. If it fits the application and the required sensitivity, you insert your sample and run it. Beckman Coulter has eight automated, application-based capillary array systems, marketed under the name P/ACE MDQ. The application-based systems—chiral, carbohydrate, molecular characterization, DNA, glycoprotein, education, and QC—differ in the way they are configured and the types of detectors and chemistries coupled to them. The carbohydrate system, for example, comes only with a LIF, whereas the molecular characterization system comes with a UV detector and a two-color LIF unit for detecting nucleic acids and proteins.
Prince Technologies offers a completely modular system, which sports a patented dynamic compression injection unit, giving <1% relative standard deviation for migration times and peak areas.
