Shodex RSPak Columns

Polymeric reversed-phase columns for applications requiring broad pH range (2-12) ideal for basic compounds as well as different selectivity from silica-based columns. Chemistries include DE-613.
Product Details

Shodex® RSpak® columns are packed with porous polymeric material that are stable at a pH range of 2-12 and have a different selectivity from silica-based columns. The wide pH range makes the chromatography of basic compounds much easier because it is possible to chromatograph at a higher pH without ion-pairing slats. Waters offers six different types of polymeric packings.
