DESCRIPTION
Nexera UC Prep stationary phases have been specifically engineered for SFC separations paying close attention to bonding coverage, density and all factors leading to high capacity phases which exhibit excellent selectivity and peak shape. The type of chemicals separated on a Nexera UC Prep Pyridyl Amide column would normally require the addition of TFA or an amine to the mobile phase as a peak shape modifier; however Nexera UC Prep Pyridyl Amide does not require this addition. Ideal for chemicals that contain both basic amine and acidic groups, as shown in the chromatogram below, Nexera UC Prep Pyridyl Amide provides flexibility for the SFC chromatographer with mobile phase composition and fraction collection greatly simplified without the use of amino additives.
