Waters, WAT046885, Delta-Pak C4 Guard Column, 300Å, 5 µm, 3.9 mm X 20 mm, 1K - 30K, 2/pk

Primarily used for legacy methods. If you are developing a new method, please consider our newer technology, BioResolve RP mAb Polyphenyl, XBridge Premier Protein BEH C4, or ACQUITY Premier Protein BEH C4 Columns for superior separation, speed, sensitivity, and resolution. Delta-Pak packings are based on a highly stable, bonded, endcapped 5µm or 15µm spherical silica. Delta-Pak is available in two different pore sizes (100Å and 300Å) with either C4 or C18 bonded phase. Delta-Pak packings are available in different cartridge and column configurations, providing consistent and predictable scale-up capabilities for milligram-to-gram scale purification. Also, by having the same chemistry available on a high-efficiency 5µm particle, you can easily check the purity of your fractions.

Additional Information
Delta-Pak C4 Guard Column, 300Å, 5 µm, 3.9 mm X 20 mm, 1K - 30K, 2/pk Delta-Pak packings are based on a highly stable, bonded, end-capped 5m or 15m spherical silica that is ideal for the separation of peptides, proteins, and natural products. Delta-Pak is available in two pore sizes (100 and 300) with either a C4 or a C18 bonded phase. Delta-Pak packings are available in a variety of cartridge and column configurations, allowing for consistent and predictable milligram-to-gram scale purification. You can also easily check the purity of your fractions by having the same chemistry available on a high-efficiency 5m particle. The 15 m packing is available in analytical-scale dimensions for preliminary preparative chromatographic analysis, peptide mapping, and fraction-purity testing. Particle size has no effect on the chemical properties of the packing materials.

FAQ
What Does Achieving High Resolution Mean in Chromatography? Since peak width and retention time, which are both essential components of the chromatographic process, are functions of resolution, resolution can be used to enhance separations. As a result, higher resolution means better and more accurate data evaluation.
