Waters™ Sunfire HPLC columns offer excellent low-pH stability and high chromatographic efficiency. They are well-suited for general purpose method development at low pH. The base material is spherical silica-gel, modified with C8 or C18 groups. Controlled manufacturing processes and column packing procedures ensure high reproducibility.
