产品说明
一般描述
Superspher® RP-18 is a reliable and versatile traditionally produced spherical silica gel carriers with C-18 reversed phase properties. They are well suited for the separation of neutral, acidic and weak basic compounds. This high performance silica carrier with a particle size of 4µm yields an excellent pressure/separation performance ratio.
