RCX-30 Analytical Guard Column Starter Kit (1 holder, 2 cartridges), PEEKRCX 30: High Exchange Capacity Anion Exchange HPLC Columns Hamilton RCX 30 columns are designed with high exchange capacity for quality carbohydrate separation. Isocratic or gradient separations can be used depending on the complexity of the mixture. A pulsed amperometric detector (PAD) is recommended for gradient separations to utilize the full potential of this column. High pH can be used to enhance carbohydrate separation on RCX 30 columns due to
