Octadecyl bonded silica gel (C18) is widely used in solid-phase extraction (SPE), but there are many variations including particle size, pore size, surface chemistry, and carbon loading applications.

EPA is updating method 525.2. The CCL3 includes 104 analytes. UCT has evaluated the recoveries of these compounds, including the current list, using proposed changes to the method with the C18-based UCT ENVIRO-CLEAN? 83 mL Extraction Cartridge ECUNI525.
