The efficient and rigorous packing technology used in J&W...

Use Discovery® C18 for any method that specifies a C18. The exceptional peak shape, reproducibility, and stability make it the column of choice for all C18 methods from demanding to routine. Legal Information: Discovery is a registered trademark of Sigma-Aldrich Co. LLC

The VersaPlate allows you to process more samples in less time with less waste. In its 96-well format, tubes are removable, making this system simpler to use and far more flexible than conventional 96-well formats. You can customize the configuration to different numbers of samples. This product is...

Agilent Microsorb is the stationary phase of choice if your ultimate goal is preparative liquid chromatography. The Microsorb column line is made up of eight different phases to address all your application needs. Four particle sizes are available which offer even more flexibility in preparative...

PLRP-S for Biomolecules products are available in a range of pore sizes and particle sizes, all with identical chemistry and fundamental adsorptive characteristics. The particles are inherently hydrophobic so there is no bonded phase, alkyl ligand required for reversed-phase separations. This gives...

Bond Elut PPL is a styrene-divinylbenzene (SDVB) polymer that is modified with a proprietary surface. PPL will retain even the most polar classes of analytes, including phenols. The large particle size allows ease-of-flow for viscous or particulate-rich water samples, while the high surface area and...

InfinityLab Poroshell 120 superficially porous columns for reversed-phase liquid chromatography (LC) separations offer exceptional efficiency and reliability. Twenty chemistries - from various C18 columns to other unique phases - are available in up to three particle diameters: 1.9 µm, 2.7 µm, and 4...

Agilent J&W CP-Sil 5 CB is a general-purpose, nonpolar column containing a 100% dimethylpolysiloxane (PDMS) phase. Separation is almost entirely based on boiling points, making this column suitable for a wide range of applications with a broad temperature range. Due to extensive crosslinking, CP-Sil...

PL aquagel-OH columns offer efficient and reliable aqueous GPC/SEC separation of water-soluble polymers and large molecules, such as PEG, polysorbate, starch, dextran, and acrylamide. PL aquagel-OH columns meet USP L25, tolerate high buffer concentrations, pH 2 to 10, temperatures up to 90 °C, and...

Bond Elut SCX is a strong cation exchanger with a very low pKa. Although the pKa is similar to Bond Elut PRS, the presence of the benzene ring in the functional group increases the potential for nonpolar interactions. This nonpolar characteristic becomes particularly important when conducting ion...

Bond Elut 96 square-well plates facilitate transfer from cartridge-based methods to 96-well plate automated formats. The 2 mL wells accommodate the larger processing volumes from older methods, easing method transfer and revalidation. When larger samples or wash volumes are required, the 2 mL well...
