Application notes

TI0732

The Scherzo SM-C18 and Unison UK-Amino columns successfully separate the small, polar ascorbic acid related compounds in normal phase mode.

TI0730

The Unison UK-Phenyl column separates surfactants of different lengths better than a standard C18 column.

TI0721

The Cadenza HS-C18 column is able to retain organotin compounds with nice, sharp peaks.

TI0713

The Scherzo SW-C18 column is able to retain compounds with multiple amine functionalities.

TI0712

The Scherzo SS-C18 column is able to retain compounds with multiple amine functionalities.

TI0703

The Scherzo SM-C18 and SS-C18 show excellent resolution of these small molecules, which normally coelute on a standard C18 column.

TI0686

Both Presto FF-C18 and Intrada WP-RP can elute this large protein. Intrada WP-RP shows sharper peaks, meaning it can better recognize its structural components than Presto FF-C18.
