The BIOshell IgG C18Guard cartridges 5x2.1mm, 2.7µm, are used for column protection of BIOshell IgG C18HPLC and UHPLC columns with an internal diameter of 2.1mm. For direct guard cartridge mounting 66841-U is used.
BIOshell columns use fused-core particles designed for biomolecules. Depending on the phase, larger pores are available for intact proteins and antibodies, medium-sized pores for peptides and oligonucleotides, and HILIC-like surfaces for glycans. The short diffusion path of the core-shell particles promotes narrow peaks, while the surface chemistry is optimized for typical bio-LC applications. As a result, BIOshell can be used for fast, sensitive, and MS-compatible bioanalytics.
