Columns are for use with basic, neutral, metal, chelating, or any other sample format, and are ideal for the separation of difficult hydrophobic samples
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 (1mm). 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 150,000 plates per meter for the 3µm particle size and 100,000 plates per meter for the 5µm 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.
