Made of highly porous monolithic rods of silica with a revolutionary bimodal pore structure, therefore high separation efficiencies are reached under low back pressures.

• Macropore size: 2 µm
• Mesopore size: 13 nm (130 Å)
• Pore volume: 1 ml/g
• Total pore volume: 3.2 ml/g
• Surface modification: aminopropyl

The major application area for amino-phases is the separation of carbohydrates (mono- and disaccharides such as fructose, glucose, sucrose, maltose and lactose), anions and organic acids. These columns may be used for normal phase chromatography, reversed phase chromatography and weak anion exchange separations.

These columns have long lifetimes within pH range of 2.5 to 7.5, high matrix tolerance and speed of analysis.
