This paper describes several application areas for a dielectric constant (DC) detector using reversed-phase liquid chromatography. It was previously reported that aqueous reversed-phase separations generally provide lower sensitivity with a DC detectors than with a refractive index (RI) detector. A smaller cell design has reduced the conductivity characteristics, so that the chromatograms produced using a modified DC detector are now comparable to those observed for an RI detector with aqueous reversed-phase carriers. The examples include triglycerides, rosin and fatty acids, fatty alcohols, gasoline samples, alpha olefins, reformer feed, and other light distillation fractions.
