Supplier: WATERS

The cartridges are compatible with the Spherisorb® cartridge system. They may also be used in a stand-alone holder or in integral extended cartridge end-fitting.

Supplier: WATERS

SymmetryShield™ columns feature Waters' patented embedded polar group technology that shields the silica's residual silanols from highly basic analytes at improves overall peak shape. Additionally, by placing the embedded polar group close to the silica surface, the activity of the surface silanols is further reduced. This imparts selectivity and retention that is different compared to the Symmetry® C18 ligand.

Supplier: WATERS

These columns are based on 4 µm silica-based particle technology. The phenyl ligand is used to achieve unique compound selectivity with reversed-phase applications.

Supplier: WATERS

The Sentry guard column holder is required for use with Sentry guard columns that have an I.D. of 3,0; 3,9 and 4,6 mm and a length of 20 mm.

Supplier: WATERS

Tetrabutylammonium hydrogen sulfate, low UV reagent

Supplier: WATERS

These cartridges can used with liquid and gas samples and have the unique capability of reverse flow direction, a useful feature for trace enrichment application.

Supplier: WATERS

The particals and chemistries of the ACQUITY UPLC columns are used to separate and with maximum speed, sensitivity and resolution without compromise, it produce the ideal combination of ultra performance efficiencies wide complementary selectivities.

Supplier: WATERS

XBridge BEH C18 sorbent can be used over an entire range of mobile phase pH (1 to 12). The trifunctionally bonded C18 ligand provides 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. The XBridge BEH C8 sorbent is less retentive compared to the XBridge BEH C18 sorbent.

Supplier: WATERS

These cartridges deliver the option of minimum sample preparation. Consists of moulded, high purity PP syringe-barrel bodies with two PE frits to contain the packing material.

Supplier: WATERS

Symmetry® C18 columns feature monofunctionally bonded C18 ligands on a high purity base-deactivated silica.

Supplier: WATERS

Styragel® HR columns are high-resolution GPC columns packed with 5 µm particles and are ideal for characterising samples in the low to mid molecular range where high resolution is critical.

Supplier: WATERS

XSelect™ CSH C18 is a general purpose column that provides alternative selectivity compared to other C18 sorbents. Charged Surface Hybrid (CSH) technology helps to overcome column related problems such as peak shape asymmetry and poor loading for basic compounds, column bleed and slow mobile-phase re-equilibration.

Supplier: WATERS

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.

Supplier: WATERS

The Envirogel™ High-Resolution GPC cleanup columns are specifically designed to remove low volatility, high molecular weight interferences such as lipids and natural resins from environmental samples as specified in EPA method 3640A.

Supplier: WATERS

The ACQUITY UPLC BEH glycan separation technology column, also known as BEH Glycan, is optimized for use with ACQUITY UPLC systems with fluorescence detection (FLR), separating the released glycans of biopharmaceuticals as their 2-aminobenzamide (2-AB) derivatives.

Additionally, by placing the embedded polar group close to the silica surface, the activity of the surface silanols is further reduced. This imparts selectivity and retention that is different compared to the Symmetry® C18 ligand.

Supplier: WATERS

These columns are suitable for a diverse range of analytes. With mobile phase (pH 1 to 12) and temperature (80 °C) compatibility, this trifunctionally-bonded alkyl column is a universal method development tool that can impact the retention, selectivity and sensitivity of ionisable compounds (with mobile phase pH) while delivering low- and high-pH stability for all analyte types.

Supplier: WATERS

These Oasis® WAX cartridges contain the WAX sorbent, which is a polymeric reversed phase, weak anion exchange mixed mode sorbent that has been optimised for fast, simple, and highly selective sample preparation of strong acidic compounds.

Supplier: WATERS

An universal, silica based bonded phase with ACQUITY HSS T3 sorbents which is used for the separations for polar and non-polar compounds. It is compatibility with 100% of aqueous mobile phase. It exhibit ultra-low MS bleed, scalable and transferable to HPLC separations.

Supplier: WATERS

XTerra® Phenyl columns are hybrid-based, reversed phase columns that incorporate phenyl ligand functionality. These first generation columns provide superior pH stability compared to a silica-based column.
