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 VF-DA is a unique, guaranteed low-bleed column for forensic drug confirmation testing. The column has high recovery for trace components and excellent resistance to direct methanol injections. Forensic drugs are measured in a variety of matrixes.

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 LTM Column Module combines a high-quality fused silica capillary column with heating and temperature sensing components for a low thermal mass column assembly. The LTM Column module has a patented design that heats and cools the column very efficiently for significantly shorter analytical cycle times compared to conventional air-bath GC oven techniques, while simultaneously using less power. 

Agilent J&W VF-1ms is a highly inert, nonpolar 100% dimethylpolysiloxane phase, ultra-low-bleed GC column providing increased sensitivity over a broad array of applications, particularly for energy, pharmaceutical, and environmental analyses. 

Agilent J&W VF-5ms is an inert 5% phenyl-methyl column for increased sensitivity, accuracy and instrument uptime. The column has the lowest guaranteed bleed specification of 1 pA at 325 °C (30 m, 0.25 mm, 0.25 µm). 

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.
