HPLC Guard Column Partisil PAC, 5.0 µm, 2 x 5 mm, 5pc/PAK

Partisil was one of the first commercially available irregular porous silicas. A large surface area gives it a high loading capacity. The columns are available with a particle size of 5µm and 10µm. Partisil PAC is a Polar Amino Cyano bonded phase with secondary amine groups for good thermal and chemical stability. Fast equilibration enables multiple separation mechanisms, including adsorption, reversed-phase and weak anion-exchange, to be used. The phase is particularly suitable for carbohydrate separations.
