High-efficiency Separations At Any pH
The Hamilton PRP-C18 is a new HPLC column designed to provide high-efficiency, reversed-phase separations over an extended column life in nearly any mobile phase or pH. The rigid stationary phase has excellent mechanical and thermal stability. ( > 100 °C), does not shrink or swell, and is completely inert to most conditions commonly encountered in reversed-phase chromatography. The PRP-C18 is a durable and effective column for general purpose HPLC and especially well-suited... (read more)
