Equisil SAS is a reversed-phase HPLC column based on fully porous, high-purity silica, bonded with short alkyl chains. This phase offers very low hydrophobic retention, making it ideal for early-eluting compounds, large molecules, or situations where minimal interaction with the stationary phase is required. Equisil SAS supports fast separations and is commonly used in method development, screening, or compound classes prone to excessive retention on C18 columns.
Equisil SAS delivers low-retention reversed-phase performance – a practical column for fast separations and special applications requiring minimal stationary phase interaction.
