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.

RP columns with unique selectivity based on diverse interactions (e.g., π-π, dipole-dipole, hydrophobic).
