High-performance columns made with ultra-high purity silica.

YMC-Pack Pro C18 columns start with a tightly controlled, highly purified silica gel, followed by a high-coverage C18 bonding, and finished with a unique endcapping procedure utilizing Lewis acid/Lewis base chemistry. Together, these features provide unequaled separations with sharp and symmetrical peaks for all types of organic molecules, especially basic pharmaceuticals and chelating compounds.
