title: Characterization of phenyl-type HPLC adsorbents.
abstract: A set of different phenyl-modified HPLC adsorbents were characterized in terms of their surface area, pore volume, and bonded phase volume using low temperature nitrogen adsorption (LTNA). Adsorbents pore volume and interparticle volume were also measured using HPLC. Comparison of the pore volumes assessed with LTNA and HPLC suggests a compact molecular arrangement for all bonded phases studied. Simple and effective method for determination of the exact mass of adsorbent and total surface area in the column is suggested.
