Preparative Columns: C2 100 Å* feature an ethyl (C2) bonded stationary phase with a 100 Å pore size, offering moderate hydrophobic interaction and fast elution for small to medium-sized analytes. With a 16% carbon load, these columns are ideal for preparative-scale purification of compounds that retain too strongly on C8 or C18 phases. They deliver sharp peak shapes, high sample loading capacity, and consistent performance—making them suitable for pharmaceutical, chemical, and natural product purification under reversed-phase conditions.
