YMC Hydrosphere C18

YMC Hydrosphere C18 Capillary Columns

The separation of polar compounds in many cases requires highly aqueous mobile phase conditions to achieve sufficient retention on the stationary phase. Conventional reversed phase selectivities do not give reproducible results under these conditions mainly due to the collapse of the C18 chains. Hydrosphere C18 has been developed, on the ultra pure silica support of the ProFamily, to be stable in 100% aqueous eluents.

    For ultra-fast LC applications YMC-Ultra HT Hydrosphere C18 with 2 µm particle size provides the optimal selectivity for the separation of highly polar compounds.

      YMC Hydrosphere is available packed in capillary columns that are compatible with all Nano and Micro LC-MS systems. Capillary columns are suitable for extremely low sample volumes and low flow rates. They are available either with 1/16" connections (10-32 thread) or with 1/32" connections (6-40 thread).
