Waters Delta-Pak Columns

Analysis and lab scale isolation of proteins or polypeptides

Delta-Pak Columns are ideal for separating and isolating peptides, proteins, and natural products. Optimized for large molecule separations and available in two pore sizes, they provide consistent and predictable scaling from milligram quantities to gram quantities between column formats.

Delta-Pak HPLC Columns are based on highly stable, bonded, endcapped 5 μm or 15 μm spherical 100% silica-based particles. These columns are offered in two different pore sizes – 100 Å or 300 Å – with either C4 or C18 ligands to address different selectivity and retentivity needs. They are available in different 15 μm cartridge and column configurations, providing consistent and predictable scale-up capabilities for milligram-to-gram scale purification. The same chemistry is also available in higher-resolving 5 µm particles, making it possible to easily check the purity of isolated fractions collected from purification chromatography.
