YMC Hydrosphere C18
YMC Hydrosphere C18 Semi-Prep 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.
YMC Hydrosphere is available in 10, 20 and 30 mm ID for semi-prep applications. YMC-Actus series columns are semi-preparative HPLC columns that have excellent column stability and efficiency as a result of combining axial compression technology with an innovative hardware design. YMC-Actus series columns show high stability under high flow rate or steep gradient conditions which is desirable for milligram to gram scale preparative HPLC of various compounds.
