Post-column addition of gradient running inverse to the eluent consistently presented a constant ~50:50 acetonitrile:water mixture to the charged aerosol detector, reducing the known bias of CAD response relative to organic composition. Partial chromatograms shown, illustrating improvements in the early (high aqueous) portion of the analysis (note peak height v. signal intensity on y-axis). Total run time was 125 min
