GC Columns
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.
Agilent J&W CP-Select CB for MTBE provides guaranteed analysis of MTBE in reformulated gasolines, with reproducible results. It has unique selectivity for ease-of-use with MTBE. The column's broad dynamic range for MTBE quantification delivers the highest productivity for increasingly demanding volatiles applications.
Agilent J&W VF-WAXms is a high performance column for applications in the food, flavor and fragrance markets, and especially where trace analyses are required.
Agilent J&W HP-PLOT Q is a bonded polystyrene-divinylbenzene (DVB) column specially developed for the separation of targeted nonpolar and polar compounds, including hydrocarbons (natural gas, refinery gas, ethylene, propylene, all C1-C3 isomers); CO2, methane, air/CO, and water; polar solvents (methanol, acetone, methylene chloride, alcohols, ketones, aldehydes, esters); and sulfur compounds (H2S, mercaptans, COS).
Agilent DB-Sulfur SCD columns are optimized for use with Sulfur Chemiluminescence Detection (SCD) to provide low bleed performance and reduced SCD ceramic tube fouling.
SLB-IL60 Ionic Liquid Capillary GC ColumnApplication: Modified (deactivated) version of SLB-IL59 provides better inertness. Selectivity more polar than PEG/wax phases, resulting in unique elution patterns. Higher maximum temperature than PEG/wax columns (300 ºC compared to 270-280 ºC). Excellent alternative to existing PEG/wax columns. Also a good GCxGC column choice. Launched in 2012.USP Code: NonePhase: Non-bonded; 1,12-Di(t…
SLB-IL59 Ionic Liquid Capillary GC Column• Application: Selectivity more polar than PEG/wax phases, resulting in unique elution patterns. Higher maximum temperature than PEG/wax columns (300 ºC compared to 270-280 ºC). Great choice for analysis of neutral and moderately basic analytes. Launched in 2009.• USP Code: None• Phase: Non-bonded; 1,12-Di(tripropylphosphonium)dodecane bis(trifluoromethylsulfonyl)imide• Temp. Limits: Su…
SUPELCOWAX® 10 Capillary GC Column• Application: This column is based on one of the most widely used polar phases, Carbowax 20M, and is a polar column suitable for analyses of solvents, fatty acid methyl esters (FAMEs), food, flavor and fragrance compounds, alcohols, and aromatics. Additionally, this column is a great choice when a polar general purpose column is required.• USP Code: This column meets USP G16 requirements.• Ph…
Equity-5 Capillary GC Column• Application: This popular column is designed for general purpose applications where a non-polar column is required. The low phenyl content provides thermal stability compared to 100% poly(dimethyl siloxane) columns.• USP Code: This column meets USP G27 and G36 requirements.• Phase: Bonded; poly(5% diphenyl/95% dimethyl siloxane)• Temp. Limits: ≤0.32 mm I.D., • Temp. Limits: ≤0.32 mm I.D., ≥2 μm: -…
