HPLC Guard Column Bio SAX, PEEK, NP 5 µm, 4.6 x 10 mm

A high performance anion exchange HPLC guard column having non-porous particles of 5.0 µm. The inner diameter and length are 4.6 mm and 10 mm, respectively. Non-porous particles are optimal for efficient mass transfer and high resolution separations.

The Bio IEX HPLC columns are designed for high resolution, high recovery and efficient separations of biological compounds such as oligonucleotides, proteins and peptides.

The Bio IEX columns are versatile for all types of biomolecules. Ion Exchange Chromatography (IEX) columns are packed with non-porous polymer particles. The Bio IEX HPLC columns are designed for high resolution, high recovery and efficient separations of biological compounds such as oligonucleotides, proteins and peptides.

The highly cross-linked and rigid non-porous poly(styrene-divinylbenzene) (PS/DVB) particles are coated with a hydrophilic polymer layer that prevents non-specific binding. Uniform, densely packed functional ion exchange groups are chemically bonded to the hydrophilic layer (multiple ion exchange groups per anchorage) to increase column capacity. The resistance of the particles, coating and bonding to high pressures enables higher resolution and faster separations. The product is suitable for a wide pH and temperature range.
