Agilent J&W DB-5ms features an excellent signal-to-noise ratio for analytical applications. 

Agilent J&W CP-Sil 88 for Dioxins has a very high polarity and a specific selectivity for dioxin and dibenzofuran separations. The column is supplied with an integrated retention gap to avoid problems with solvent condensation, thus allowing repeated splitless injections without phase deterioration, extending column life. 

Agilent J&W DB-1ms and HP-1ms Ultra Inert deliver consistent column inertness performance to ensure sensitivity, performance, and integrity. With excellent peak shapes, exceptionally low bleed and high signal-to-noise ratios, DB-1ms and HP-1ms Ultra Inert perform effectively with even the most challenging active analytes.

Agilent J&W DB-FastFAME is a cyanopropyl phase engineered for the fast and selective separation of polysaturated and unsaturated FAMEs—even challenging cis and trans FAME isomers—without sacrificing the resolution generally achieved with traditional 100 meter long columns.

The Select FAME column is tuned for optimal cis/trans separations of FAMEs, especially the C18 isomers. The bonded column has an isothermal maximum operation temperature of 275°C and a programmed temperature of 290°C - a dramatic improvement of 50°C compared to non-bonded columns. Select FAME has better detection limits because the column has a very low bleed level. Even though this is a very polar column, the column efficienc…

Agilent J&W DB-WAX is ideal for food, fragrance, and flavor applications. The column's lower temperature limit of 20 °C improves resolution of analytes with low boiling points.

Agilent J&W HP-Chiral ß has a chiral stationary phase based on permethylated beta-cyclodextrin, which has very broad applications for resolving volatile optical isomers. Beta-cyclodextrin is dispersed in a phenyl-based polymer. This polymer provides low bleed and will not interfere with nitrogen-specific detectors such as the nitrogen phosphorus (NPD) detector, allowing optimized sensitivity for chiral compounds containing ni…

HiTrap Protein A HP are prepacked columns for routine preparative purification of monoclonal and polyclonal antibodies such as human IgG.

Agilent J&W Biodiesel GC columns are purposely designed and application-optimized for the analysis of biodiesel to meet the ASTM and CEN testing standards

The Agilent J&W Cyclo Sil-B GC Columns perform chiral separations without chiral specific derivations. Agilent makes more capillary columns than anyone else in the world and our commitment to product reliability and repeatability has raised the level of quality that chromatographers demand. We continue to tighten our performance criteria such as separation efficiency, retention characteristics, peak height ratios, and bleed ra…

DuraGuard columns are made with a single, continuous piece of tubing consisting of a built-in length of deactivated fused silica tubing and an analytical column. Difficult samples, such as pesticides or drugs, can be analyzed without any undesirable contributions from the unions.

Agilent J&W CP-Carbowax 400 for Volatiles in Alcohol has the highest resolution for amyl alcohols, for accurate quality control. Its high plate number, even at 0 °C, delivers for reliable analysis of the most volatile compounds. It is specially designed and tested for this application, ensuring performance and column-to-column reproducibility.

This leading-edge column technology is ideal for applications that require faster run times, such as high-throughput screening, fast process monitoring, and fast method development. Agilent High Efficiency GC columns can reduce sample run time by 50% or more without compromising resolution.

Agilent J&W DB-1ht delivers excellent performance in a range of GC/MS applications and are manufactured to the highest levels of quality and stability. Nonpolar DB-1ht columns are specially processed for operation up to 400 °C, with optimized, polyimide-coated fused silica tubing. 

Agilent J&W DB-ALC1 and DB-ALC2 analytical column enable two minute analyses by reducing run time by one-third compared to other blood alcohol analysis columns.

Agilent J&W HP-Fast Residual Solvent columns are equivalent to U.S.P phase G43. They feature a thinner film that reduces run times by a factor of 2.5 compared to columns of standard film thickness. These HP-Fast Residual Columns are bonded and cross-linked.

Agilent J&W HP-1ms is a high quality, 100% dimethylpolysiloxane, nonpolar phase with identical selectivity to HP-1. HP-1ms are excellent general purpose columns, with low-bleed characteristics and improved signal-to-noise ratios.

Agilent J&W HP-5ms has very low bleed characteristics that are ideal for GC/MS. The column has excellent inertness for active compounds, including acidic and basic compounds, and improved signal-to-noise ratio for better sensitivity and mass spectral integrity.

Agilent J&W DB-ProSteel metal columns are deactivated with a special process treatment formula to provide good inertness. The columns can be custom-wound on request for small GC ovens. DB-ProSteel has the same outer diameter as standard megabore columns of 0.53 mm id so no special ferrules are required for proper installation.

Agilent J&W HP-101 is a 100% dimethylpolysiloxane phase. It is not bonded or cross-linked, and is therefore useful for established methods that do not require the column to have cross-linked or bonded polymer phases. Note: Because HP-101 columns are not bonded or cross-linked, we do not recommend solvent rinsing.

Agilent J&W Carbowax 20M and HP-20M are polyethylene glycol (PEG) columns equivalent to USP phase G16. Their temperature range of 60 to 220 ºC is ideal for alcohols, free acid, ether, glycol, and solvents. Carbowax 20M and HP-20M are not bonded or cross-linked and so solvent rinsing is not recommended. DB-WAX is the bonded alternative for HP-20M.

Agilent J&W Select PAH is the first capillary column that provides a single solution for PAH analysis by separating all the isomers, thereby avoiding false positives and inaccurate results. It provides easy, fast, and accurate quantification of PAHs in environmental and food samples by resolving PAH isomers.

Agilent J&W DB-EUPAH columns are designed and tested to provide the most optimal performance for all 16 EU-regulated polycyclic aromatic hydrocarbons (PAHs). The columns are individually tested with an application-specific QC test probe mixture and deliver excellent resolution of critical PAH isomers, such as benzo(b,j,k)fluoranthene.

Agilent J&W CP-Sil PAH CB UltiMetal combines the advantages of a highly thermo-stable stationary phase with UltiMetal stainless steel as the column material. This unique column separates all 16 PAHs according to EPA method 610. 

Agilent J&W HP-PAS5 nonpolar columns are specifically designed and processed for the analysis of organochlorine pesticides. With an operating temperature range of -60 to 325/350 ºC, all HP-PAS5 columns are ECD-tested to assure minimal pesticide breakdown and low ECD bleed.
