Based on Core Enhanced Technology, using 4 µm solid core particles, these columns allow users of conventional HPLC methods to enjoy performance far beyond that of columns packed with 5, 4 or even 3 μm fully porous particles. Very high separation efficiencies, using standard HPLC instruments and conditions, provide increased peak resolution and lower limits of detection. An ultra-stable packed bed results in exceptionally robust columns that demonstrate excellent retention and response reproducibility.
