Thermo Fisher, 28105-253030, Hypersil™ BDS C18 Columns

Hypersil™ BDS C18 is a base-deactivated reversed-phase HPLC column for robust general-purpose separations in QC and analytical laboratories. This configuration uses 5 µm particles in a 3.0 × 250 mm analytical column. The BDS treatment reduces residual silanol activity, improving peak shape for basic and polar analytes compared with untreated silica phases. The C18 bonded phase provides broad hydrophobic retention and is suitable for pharmaceuticals, food components, environmental compounds, and many routine small-molecule methods. The stationary phase has approximately 130 Å pores and operates over a stated pH range of about 2–8. The long 250 mm format provides high efficiency and resolving power for established HPLC methods.
