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 CP-Sil 8 CB for Pesticides delivers a linear column response down to femtogram levels. The column is supplied with an intergrated retention gap to avoid problems with solvent condensation, thus allowing repeated splitless injections without phase deterioration.

Agilent J&W Select Low Sulfur meets the specific needs of petrochemical chemists who need lower detection limits for sulfur components in propylene. This column provides significantly lower detection limits due to the highest inertness towards volatile reactive sulfur components.

Agilent J&W CP-SimDist UltiMetal performs extended analysis to C120, and is guaranteed to a Tmax of 450 °C, due to the virtually unbreakable inert UltiMetal tubing. The internal diameter of UltiMetal tubing is the same as for fused silica 0.53 mm id (Megabore) columns, providing trouble-free automation of on-column injection. 

Agilent J&W CP-Wax 51 for Amines is designed for the analysis of C4-C10 amines, diamines and aromatic amines. The column conforms to EPA method 607.

Agilent J&W DB-Petro is a 100% dimethylpolysiloxane phase, precision-engineered for the analysis of PONA, PIANO and PNA from petroleum processes. These high resolution DB-Petro columns are bonded, cross-linked, and solvent rinsable, and have been extensively QC tested to the strictest industry standards. 

PoraBOND Q is the long-term solution for analyzing volatile solvents and hydrocarbons. It is the most stable column of its kind and withstands repeated later injections. Due to our manufacturing techniques, the porous polymer is very pure and has virtually no catalytic activity. 

Agilent J&W HP-FFAP is designed primarily for the analysis of organic acids, free fatty acids, or samples that require quantitation of acidic impurities. The FFAP stationary phase is modified with acid to provide a very inert column that can accommodate the demanding analysis of acids dissolved in water. 

CP-Wax 52 CB GC columns have lower minimum temperature and a higher maximum temperature than non-bonded polyethylene glycol (PEG) columns due to extensive cross linking, delivering higher resolution of low-boiling-point analytes. With guaranteed reproducibility and excellent temperature stability, CP-Wax 52 CB is ideal for EPA and ASTM methods.

Agilent J&W CP-Sil 5 CB is a high efficiency column containing a 100% dimethylpolysiloxane phase. Separation is almost entirely based on boiling points, making this column suitable for a wide range of applications with a broad temperature range. 

Agilent J&W HP-88 is designed for the separation of fatty acid methyl esters (FAMEs). It provides greater cis/trans resolution than the DB-23, and has nearly identical selectivity as the CP-Sil 88, but with higher temperature limits. 

Agilent J&W Ultra 1 is a 100% dimethylpolysiloxane, nonpolar column that resembles HP-1 but with tighter specifications for retention index and capacity factors. Agilent J&W Ultra 2 is a (5%-phenyl)-methylpolysiloxane, nonpolar column and resembles HP-5 but with tighter specifications for retention index and capacity factors. 

Agilent J&W DB-35 columns are ideal for conformational analysis. The DB-35 is a (35%-phenyl)-methylpolysiloxane, mid-polarity column with low bleed. 

Agilent J&W DB-1 is non-polar and low-bleed, and operates under high temperature limits. It is an excellent choice for general purpose use in a wide variety of applications. 

Agilent J&W HP-5ms Semivolatile columns are specifically tested for inertness for active compounds, including acidic and basic compounds. With an effective operating temperature range of -60 to 325/350 ºC, these nonpolar columns offer industry-leading levels of sensitivity and analysis integrity. All columns are tested to Agilent's demanding QC industry standards and are bonded, cross-linked and solvent rinsable.

Agilent J&W DB-Dioxin columns are specifically engineered for the analysis of polychlorinated dibenzodioxins (PCDD) and dibenzofurans (PCDF). The column resolves 2,3,7,8-TCDD and 2,3,7,8-TCDF from all other isomers in one run.

Total petroleum hydrocarbon analysis is a routine technique in many environmental laboratories, with many samples needing to be screened. A simple and reliable method is required that provides the shortest analysis time. 

Agilent J&W DB-VRX features unique selectivity, engineered for optimum resolution of volatiles. The low-polarity DB-VRX columns deliver excellent peak shapes and are fully compliant with U.S. EPA methods 502.2, 524.2, and 8260.
