Reversed Phase HPLC Columns

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.

PRP-1
Polymeric 100A columns for broad ranging uses, similar to a C-8, C-18 column

PRP-1 Analytical Cartridge Columns
Rapid gradient separations, sample concentration and screening of sample mixtures

HxSil C8, C18
Silica-based columns for high efficiency separation of a wide variety of compounds

PRP-3
Polymeric 300A columns for gradient protein and peptide separations

PRP-Infinity
Polymeric, nonporous columns for fast gradient separations of large proteins or peptides

Bulk Resins
Preparative/process scale purifications
