HPLC Guard Columns and Cartridges
Waters Corp Atlantis dC18 Prep Guard Cartridge, 100Å, 5 µm, 10 mm X 10 mm, 1/pk
Atlantis dC18 columns are universal, silica-based, reversed-phase C18 columns that are used for polar compound retention. The Atlantis dC18 columns feature di-functionally bonded C18 ligands that have been optimized for use with highly aqueous mobile phases, including 100% water.
Waters Corp XBridge BEH Shield RP18 Sentry Guard Cartridge, 130Å, 5 µm, 4.6 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 Shield RP18 Sentry Guard Cartridge, 130Å, 3.5 µm, 4.6 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, 2.1 mm X 10 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 Shield RP18 Sentry Guard Cartridge, 130Å, 3.5 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 C18 Sentry Guard Cartridge, 130Å, 5 µm, 4.6 mm X 20 mm, 2/pk
As a workhorse for HPLC method development, XBridge BEH C18 sorbent can be used over an entire range of mobile phase pH (1-12). The trifunctionally bonded C18 ligand provides you with a universal column for most HPLC separations and gives you the widest usable pH range, superior low pH stability, and ultra-low column bleed.

Waters Corp SunFire C8 Prep Guard Cartridge, 100Å, 10 µm, 10 mm X 10 mm, 1/pk
SunFire C8 columns are used for general purpose method development at low pH. The C8 ligand is preferred for some assays because it is less hydrophobic and therefore less retentive compared to SunFire C18.
Waters Corp SunFire C18 Prep Guard Cartridge, 100Å, 10 µm, 10 mm X 10 mm, 1/pk
SunFire C18 columns are used for general purpose method development at low pH. The C18 ligand is highly retentive, especially for basic compounds and it is ideally suited for purification and impurity profile assays.
Waters Corp Torus 2-PIC Prep Guard Cartridge, 130à , 5 µm, 19 mm X 10 mm, 1/pk

Sepax Technologies Inc Sepax HPLC Column HPLC Guard Cartridge (No Holder), Proteomix SAX, NP5, 4 x 10 mm
Proteomix ion-exchange phases have been innovatively developed for achieving high ion-exchange capacity, a breakthrough technology for non-porous resins. Proteomix packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead with particle size selections of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. The hydrophobic PS/DVB resin surface is totally covered by a hydrophilic coating that eliminates non-specific bindings with biological analytes, leading to high efficiency and high recovery separations for biological molecules.
