On-line multichannel Raman spectroscopic detection system for capillary zone electrophoresis.

An on-line multichannel Raman spectroscopic detection system for capillary zone electrophoresis using a charge-coupled device as the detector is described. Resonant, near-resonant and non-resonant excitation Raman spectroscopies are employed. The 400 cm-1 spectral window provides adequate information to identify resolved and unresolved compounds. The use of analyte velocity reduction to allow i...

On-Line Radioisotope Detection for Capillary Electrophoresis

Two simple, on-llne radloactlvlty detectors for Capillary electrophoreds are descrtbed. The first caplllary electrophoresls/radioisotope detector system utlllres a commerclally available semlcMKhtctor devloe, which is positioned external to the Separation channel and whlch responds dlrectly to lmpkrshrs y or hlgh-energy @ radlatlon. The second caplllary electrophoreds/radtope detector uttllzes ...

Detection of monoclonal proteins by capillary zone electrophoresis: comparison of 2 multichannel automated systems.

To the Editor: Capillary zone electrophoresis (CZE) is an alternative method for separation of serum proteins (1 ). Two dedicated and automated multichannel instruments are available, the Paragon 2000 (Beckman-Coulter) and the Capillarys (Sebia). The sensitivity and specificity of Paragon 2000 for detection of monoclonal proteins have been reported to be 95% (2–4) and 78% (4 ), respectively. Th...

Two-dimensional capillary electrophoresis: capillary isoelectric focusing and capillary zone electrophoresis with laser-induced fluorescence detection.

CIEF and CZE are coupled with LIF detection to create an ultrasensitive 2-D separation method for proteins. In this method, two capillaries are joined through a buffer-filled interface. Separate power supplies control the potential at the injection end of the first capillary and at the interface; the detector is held at ground potential. Proteins are labeled with the fluorogenic reagent Chromeo...
