Waters Delta-Pak C18 Guard Column, 100å, 5 Μm, 3.9 Mm X 20 Mm, 1k - 15k, 2/Pk

Primarily used for legacy methods. If you are developing a new method, please consider our newer technology, XSelect Premier Peptide CSH C18, XBridge Premier Peptide BEH C18, or ACQUITY Premier Peptide BEH C18 or CSH C18 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.
