Waters Corp XBridge BEH Shield RP18 Sentry Guard Cartridge, 130Å, 5 µm, 3 mm X 20 mm, 2/pk
XBridge BEH Shield RP18 columns complement the XBridge BEH C18 and C8 phases and provide a necessary and powerful tool for HPLC method development. The embedded carbamate group in the bonded phase ligand provides alternate selectivity, especially for phenolic compounds compared to straight chain alkyl columns.
Waters Corp XBridge BEH C8 Sentry Guard Cartridge, 130Å, 5 µm, 3 mm X 20 mm, 2/pk
The XBridge BEH C8 sorbent is less retentive compared to the XBridge BEH C18 sorbent. Anyone developing methods may prefer the speed offered by a less retentive column, while improving peak shape and chromatographic performance. The trifunctionally bonded sorbent offers you the widest usable pH range (1-12), superior low pH stability, and ultra-low column bleed.
Waters Corp XBridge BEH Phenyl Prep Guard Cartridge, 130Å, 5 µm, 19 mm X 10 mm, 1/pk
XBridge BEH Phenyl columns provide complementary selectivity to C18 stationary phases, especially for polyaromatic compounds. This most chemically stable commercially available Phenyl sorbent on the market and provides you with ultra-low column bleed, long column lifetimes and excellent peak shape.
Mac-Mod Avantor Prevail Amino, 110 Å, 5 µm, 4.6 x 7.5 mm Guard Cartridges (3/pk)
Avantor Prevail HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. Avantor Prevail HPLC columns are silica based except for Prevail Carbohydrate ES. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes. Avantor Prevail HPLC columns are stable from highly organic to highly aqueous. Avantor Prevail HPLC columns are specialty phases for specific applications. Avantor Prevail HPLC columns provide excellent sensitivity with microbore and ELSD applications.
