Waters Corp BIORESOLVE RP MAB POLYPHENYL V
BioResolve RP mAb Polyphenyl VanGuard Cartridge, 450A, 2.7 um, 3.9mm X 5mm, 3/pkg;Silica, 1 - 8 Ph Range, Low Silanol Activity, End Capped , Spherical , 5.5 % Carbon Load
Waters Corp SunFire C18 Prep Guard Cartridge, 100Å, 5 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 SunFire C18 Sentry Guard Cartridge, 100Å, 3.5 µm, 4.6 mm X 20 mm, 2/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 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, 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 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, 4.6 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 SunFire C8 Prep Guard Cartridge, 100Å, 5 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 BioSuite Diol (OH) Guard Column, 4 µm, 4.6 mm X 35 mm, 10K - 500K, 1/pk
BioSuite SEC Columns are available in 4.6 mm, 7.5 mm, and 7.8 mm i.d. analytical and 21.5 mm i.d. preparative and guard columns.
