Monoclonal-like peaks in alfa2-beta region caused by radio-contrast media on capillary zone electrophoresis

Technique to remove interference caused by radio-opaque agents in clinical capillary zone electrophoresis

To the Editor: We read with great interest the report “Interference of Radio-opaque Agents in Clinical Capillary Zone Electrophoresis” (1 ). A laboratory sent two similar patient samples for our evaluation. Both patients had received intravenous sodium meglumine ioxitalamate (Telebrix), a radioopaque contrast material that absorbs at 214 nm. The interfering substance was not visible on agarose ...

Isotachophoresis superimposed on capillary zone electrophoresis

Applying isotachophoresis (ITE’) superimposed on capillary zone electrophoresis (CZE), which will be denoted the ITPlCZE mode, components migrate in an ITP way on top of a background electrolyte. In such an ITPKZE system the leading electrolyte consists of a mixture of an ionic species L, with a high mobility (the leading ion of the ITP system), an ionic species L, with low mobility (the co-ion...
