TSKgel Octadecyl-NPR, 2.5 µm, non-porous 35 mm x 4.6 mm

The TSKgel Octadecyl-NPR HPLC column 35x4.6mm, 2.5µm, contains non-porous polymethacrylate particles with a hydrophobic C18 surface. The absence of internal pore diffusion enables rapid mass transport and short gradients, but limits loading capacity compared with porous phases. TSKgel Octadecyl-NPR is used for fast protein and peptide separations.

Features and Benefits

• Virtually all LC separation mechanisms under one brand
• Silica and polymer materials for small molecules through biopolymers
• Graded pore sizes for SEC and GPC
• Analytical, UHPLC, and semipreparative formats
• Co-phase protective systems for many product lines

Additional Information

The TSKgel product line includes silica-based and polymer-based packing materials for size-exclusion chromatography, gel permeation chromatography, reverse-phase chromatography, HILIC, ion-exchange chromatography, hydrophobic interaction chromatography, and affinity chromatography. Silica is primarily used for highly efficient SEC and RP columns. Hydrophilic polymethacrylates enable aqueous SEC and bioseparations, while polystyrene-divinylbenzene covers organic GPC. Non-porous particles provide particularly fast mass transport; porous particles, on the other hand, offer higher capacity or a defined molecular weight range. Selecting the appropriate pre-column or cartridge extends its service life, but it must always be compatible with the specific TSKgel family and ID.
