HPLC Guard Columns and Cartridges
Waters Corp Spherisorb Cyano (CN) Guard Cartridge, 80Å, 5 µm, 4.6 mm X 30 mm, 3/pk
The Spherisorb CN chemistry is general purpose normal phase propyl cyano bonded ligand to a silica substrate. This column is conditioned and shipped with normal phase solvent.
Waters Corp Spherisorb SCX Guard Cartridge, 80Å, 5 µm, 4.6 mm X 30 mm, 3/pk
Spherisorb SCX columns contain an anionic silica-based sorbent. This strong cation- exchange sorbent is used to separate positively charged ionic species.
Sepax Technologies Inc Sepax HPLC Column PolyRP-100, 10 µm, 4 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Waters Corp XBridge BEH C18 Sentry Guard Cartridge, 130Å, 3.5 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 C8 Sentry Guard Cartridge, 130Å, 3.5 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 SunFire C8 Sentry Guard Cartridge, 100Å, 3.5 µm, 3 mm X 20 mm, 2/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 C8 Sentry Guard Cartridge, 100Å, 5 µm, 2.1 mm X 10 mm, 2/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 Symmetry C4 Sentry Guard Cartridge, 300Å, 3.5 µm, 2.1 mm X 10 mm, 2/pk
Symmetry columns continues to set the standard for HPLC drug assays, giving you confidence in the long-term compliance of your HPLC methods. No need to compromise on peak shape, selectivity, column-to-column and batch-to-batch reproducibility, or other critical performance characteristics. Available in a variety of particle sizes, chemistries and dimensions.
Waters Corp Symmetry C4 Sentry Guard Cartridge, 300Å, 5 µm, 3.9 mm X 20 mm, 2/pk
Symmetry columns continues to set the standard for HPLC drug assays, giving you confidence in the long-term compliance of your HPLC methods. No need to compromise on peak shape, selectivity, column-to-column and batch-to-batch reproducibility, or other critical performance characteristics. Available in a variety of particle sizes, chemistries and dimensions.
