Gas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.
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 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 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.
Agilent J&W DB-608 columns are precision-engineered to deliver industry-leading performance in the effective analysis of chlorinated pesticides and PCBs. DB-608 widely used for U.S. EPA methods 608, 508, and 8080, and deliver excellent inertness and recoveries, without resulting in pesticide breakdown.
Agilent J&W VF-5 Pesticides columns are specially designed for the determination of trace levels of pesticide residue. Every column is individually tested before shipment with key pesticides, including endrin and aldrin, ensuring optimal performance and consistency of results.
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 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-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.
