Purospher™ STAR columns are designed to provide optimum results even when loaded with large or small sample volumes and are also available in a narrow-bore format (1 mm). The wide pH range provides the required pH stability for 99% of the common analysis applications. These columns provide the power to separate even the most difficult of compound mixtures. With up to 150000 plates per meter for the 3 µm particle size and 100000 plates per meter for the 5 µm particle size, Purospher™ STAR columns ensure good baseline separations. Special derivatization and endcapping processes ensure long-term chemical stability, excellent retention stability, and long column lifetime. All Purospher™ STAR columns are guaranteed to provide absolutely reproducible results.
