YMC-Pack ProFamily

YMC ProFamily is based on a silica with an extremely low metal content. Low metal content suppresses polar interactions, as metal impurities cause silanol groups to become more acidic. This provides YMC ProFamily excellent resolution for a wide range of compounds, especially basic pharmaceuticals.

To minimise the unwanted interactions between residual silanols and the sample molecules that are responsible for asymmetric peaks, YMC utilises a proprietary, highly effective endcapping process.

Important for every chromatographer: YMC ensures that the physical properties e.g. particle size, pore size, metal content are extremely reproducible from LOT to LOT.
