These columns provide excellent peak shape with basic compounds due to the advanced end capping technology employed to reduce residual silanol activity.

• Consistently reproducible quality
• Documentation of each manufacturing step
• Consistently high packing quality and column efficiency
• Stringent specifications
• Individual test of each column
• Lot identification for each column

The ultrapure silica and very low residual silanol activity makes reduces the use of ion-pairing reagents or ion-suppression techniques, making them ideal for LC/MS applications.

Surface hydrophobicity is lower than that of ODS, this ensures fast analysis of compounds of greatly differing hydrophobic properties. Ideal for the analysis of all types of organic molecules, but specifically basic and metal chelating compounds.

These can also be useful for separation of hydrophilic and planar compounds in cases where resolution is hard to achieve on ODS materials.
