Chromegabond Series Chromatography Column, 150x4.6mm 5µm, 135221-DNAP-II (CAT#: STEM-C-2672-ZJF)

Chromegabond is a high-alkaline deactivated stationary phase produced through a two-step process. The first step involves bonding monomeric ligands such as C18, C8, C4, phenyl, cyano, or biphenyl to synthetically produced ultra-high purity spherical silica. The second step uses a proprietary multi-endcapping bonding process to create a high-alkaline deactivated column. This advanced bonding method reacts short-chain alkyl silanes with residual silanol groups.
Chromegabond WR is particularly suitable for amines and acids, offering an alternative selectivity to the Epic series LC columns. Compared to the Epic series, Chromegabond WR employs a different silica with a smaller surface area. In many cases, different silicas can provide varying retention capabilities and selectivity, making Chromegabond WR an excellent choice for specific analytical needs.
