Poly 30RPC / Poly 15RPC Reversed Phase Chromatography Resins are monodisperse resin materials developed by globally advanced high-throughput microfluidic technology. The resins utilize highly cross-linked polystyrene/divinylbenzene as the matrix framework. Due to the abundant phenyl groups within the matrix, hydrophobic interactions occur with non-polar groups of separated substances, resulting in chromatographic retention behavior similar to silica-based reversed phase chromatography.
