WebThis chapter illustrates the usefulness of capillary zone electrophoresis (CZE) coupled to high-resolution electrospray ionization quadrupole time-of-flight mass spectrometry for the single-step desalting, and separation, as well as characterization of oligonucleotides in the framework of quality control after synthesis. WebNote: In CZE there is buffer between analyte bands. "All" that's required in the CZE method is a well-chosen buffer in the initial buffer reservoir. Separation occurs because of relatively simple interaction of the analytes with the pH of the buffer. This technique is also called free solution capillary electrophoresis (FSCE) for that reason.
