General, chemical type or category of compound to be separated.
The type of resin that is packed inside the column tube.
United States Pharmacopeia HPLC column designation.
Size (in micrometers) of the polymer or silica bead packed inside the column tube.
Inside diameter (in millimeters) of the column tube.
Length of the column tube (in millimeters).
PRP Polymeric Reversed Phase Poly(styrene-divinylbenzene) HPLC Columns are used in quality assurance as well as research and development laboratories because they last significantly longer than silica-based reversed phase columns. This is particularly true for difficult analyses like: high pH samples (pH 8-13); labile or reactive samples (irreversible adsorption); high aqueous purifications (80-100% water); and separations with ion pairing reagents. HxSil silica-based columns are ideal for applications where a higher efficiency reversed phase C8 or C18 column is needed.
