YMC-Pack Pro C18 RS Analytical Guard Columns

Ultra-pure Silica-based C18

The YMC Pro Family 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 ensures YMC Pro Family phases provide excellent resolution for a wide range of compounds, especially basic pharmaceuticals.  To minimize the unwanted interactions between residual silanols and the sample molecules that are responsible for asymmetric peaks, YMC utilizes a proprietary, highly effective endcapping process.  Important for every chromatographer: YMC ensures that the physical properties, such as particle size, pore size, and metal content, are extremely reproducible from lot to lot.  YMC-Pack Pro C18 RS offers excellent peak shape for basic compounds due to extensive endcapping of the stationary phase, and also exhibits high recognition of stereoselectivity because of high-carbon polymeric-type bonding (22% carbon load).


Features & Benefits – Analytical Guard Cartridges

YMC’s Guard Column Cartridge Systems for HPLC accept cartridges of 1.0, 2.1, 3.0, or 4.0mm analytical-guard-columnsinner diameters – in either 10mm or 20mm lengths.  Cartridges are available with a comprehensive selection including all stationary phase chemistries offered by YMC, ensuring compatibility between the guard column and the analytical column.  Assembly is tool-free, simplifying cartridge replacement.

YMC Guard Column Cartridges require the use of a holder, P/N: XPGCHP1 for 10mm length and P/N: XPGCHP2 for 20mm length.
