HPLC column of the ISAspher line guarantee the highest possible reliability in a wide range of applications.

• The production of the silica used as well as the functionalisation are carried out according to highly developed and validated process
• Reliable and proven
• Flexibility and robustness for every HPLC application

This ensure unchanged properties of the stationary phases in terms of selectivity and consistent chemical properties.

Direct scale-up e.g. starting from a particle size of 5 µm to semi-preparative or preparative applications (up to 45 µm particle size) can be easily implemented. Of course, the same applies for a scale-down, e.g. to a 3 µm particle size, if a speed-optimised analytical method has to be established.

C18 columns with integrated polar group (polar embedded). Additional polar interactions, stable with solely aqueous eluents. Amongs other suitable for neutral, acidics and basic analytes.
