Agilent J&W CP-Sil 8 CB is a general-purpose phase that incorporates 5% phenyl groups in the dimethylpolysiloxane polymer, giving it slightly higher polarity than CP-Sil 5 CB. This delivers better selectivity for aromatic compounds and makes it the best choice for method development. Equivalent to...

Agilent J&W DB-Petro is a 100% dimethylpolysiloxane phase column, precisely engineered for the analysis of PONA, PIANO, and PNA from petroleum processes. These high-resolution gas chromatography (GC) columns are bonded, crosslinked, and solvent rinseable. DB-Petro columns have been extensively...

Agilent J&W HP-35 is a mid-polar GC column that incorporates a (35% -phenyl)-methyl polysiloxane phase specified by EPA method 8081 and USP G42. The intermediate polarity makes it well suited for the analysis of pesticides, herbicides, pharmaceuticals, and amines. This product is only available to...

The Agilent Technologies 5 um PLgel repair gel is suitable for use with GPC columns. This product is only available to U.S. Domestic Customers. For research use only, not to be used in diagnostic procedures.

Empty SPE Tubes allow you to pack your own SPE cartridges.

Eclipse Plus C18 columns are designed for superior peak shape with basic compounds and deliver high efficiency and excellent peak shape with all sample types. Eclipse Plus C18 is especially useful for the separation of acidic, basic, and other highly polar compounds by reverse-phase liquid...

Agilent provides a range of high-performance column ferrules for various third-party gas chromatography instruments, including PerkinElmer, Thermo Scientific and Varian/Bruker. Graphite, Vespel/graphite, and Vespel column ferrules create consistent, leak-free seals with minimum torque. All column...

Gas Chromatography (GC) columns are at the heart of the gas chromatograph and responsible for the separation process. GC is one of the most important and critical tools in analytical chemistry, because of its effectiveness, sensitivity and ease-of-use. GC columns contain a stationary phase,...

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...

J&W Packed Gas Chromatography (GC) Columns are designed and manufactured to offer excellent and reproducible performance for all sample types associated with packed column separations, most important in the hydrocarbon processing industry. The efficient and rigorous packing technology used in J&W...

Native silica is generally regarded as the most polar SPE sorbent available. Bond Elut SI is effective at separating compounds with very similar structures. Applying the analytes in a nonpolar solvent, then increasing the solvent polarity by increasing the concentration of a polar modifier, such as...

Bond Elut Plexa polymeric SPE offers straightforward, easy-to-use methods that simplify sample preparation processes. The water-wettable, hydroxylated exterior allows excellent flow, even with biological fluids. A gradient of polarity on the polymer surface shunts small analytes to the more...

proprietary Crossbond phase Many laboratories analyzing organochlorine pesticides struggle with breakdown and adsorption of endrin, DDT, and methoxychlor caused by active sites throughout the analytical system. Siltek passivation technology enables these columns to offer unsurpassed inertness 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...

(50%-Phenyl)-methylpolysiloxane Midpolarity slightly more polar than HP-50+ Suitable for confirmational analyses Bonded and cross-linked Solvent rinsable Temperature limits are 40° to 260/280°C or 40° to 280/300°C Equivalent to USP Phase G3 HP-50+, Rtx-50, CP-Sil 24 CB,...

Agilent Technologies products are intended for sale/shipment within the US only. International customers should contact their local Agilent Technologies distributor to place orders for Agilent Technologies products.

The Agilent J&W DB-HeavyWAX Polyethylene Glycol (PEG) is a high-temperature WAX column that can operate at higher maximum temperatures (280 °C isothermal, 290 °C programmed) than standard WAX columns. This allows for shorter run times, providing a lower cost per test. The column provides retention...

Agilent J&W CP-Sil 8 CB is a general-purpose phase that incorporates 5% phenyl groups in the dimethylpolysiloxane polymer, giving it slightly higher polarity than CP-Sil 5 CB. This delivers better selectivity for aromatic compounds and makes it the best choice for method development. Equivalent to...

Agilent ZORBAX fully porous particle columns for normal phase HPLC and supercritical fluid chromatography (SFC) are designed for the retention and separation of lipophilic compounds. The unique ZORBAX chemistries deliver outstanding efficiency in both achiral SFC and normal phase chromatography due...
