Separation of phenols as neutral compounds by micellar electrokinetic capillary chromatography
Separation of phenols as neutral solutes by micellar electrokinetic capillary chromatography provides a quantitative linear dynamic range of 6000–13 000. Since the compounds are injected and separated as neutral solutes, the dispersive processes of anti-stacking and electrodispersion are eliminated....

Summary: | Separation of phenols as neutral solutes by micellar electrokinetic capillary chromatography provides a quantitative linear dynamic range of 6000–13 000. Since the compounds are injected and separated as neutral solutes, the dispersive processes of anti-stacking and electrodispersion are eliminated. Optimized conditions allow for sub-ppm quantitation of trace impurities in the presence of the major components at various stages of the production of high purity phenols. The background electrolyte consists of 100 m
M sodium dodecyl sulfate in 50 m
M phosphate buffer pH 7. The method is precise, reliable, and the limits of detection are superior compared to HPLC by a factor of 20. |
