GC Columns Products & Reviews

Agilent ® J&W™ DB-5ms and HP-5ms Ultra Inert deliver industry-leading analytical performance in a range of chromatographic applications. Very low bleed characteristics and excellent signal-to-noise ratio and peak shapes, enables high levels of performance in analyzing challenging active analytes. DB-5ms  and HP-5ms Ultra Inert are also individually tested with a demanding Ultra Inert test probe mixture, to deliver consistent…

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.

SP-2560 Capillary GC Column• Application: This highly polar biscyanopropyl column was specifically designed for detailed separation of geometricpositional (cis/trans) isomers of fatty acid methyl esters (FAMEs). It is extremely effective for FAME isomer applications.• USP Code: This column meets USP G5 requirements.• Phase: Non-bonded; poly(biscyanopropyl siloxane)• Temp. Limits: Subambient to 250 °C (isothermal or programmed

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.

Agilent J&W DB-1ms is a nonpolar, low bleed column, with excellent inertness for acids and bases and an extended upper temperature limit. Using low bleed stationary phases in DB-1ms reduces column contribution to background noise, resulting in a higher signal-to-noise ratio and better sensitivity. 

- Optimized column selectivities guarantee resolution of ethanol, internal standards, and frequently encountered interferences. - Robust and reproducible column chemistry ensures longer column lifetime and consistent results. - 2 minute analysis time increases lab productivity. - Stable to 260 °C Don’t forget: Blood alcohol analysis requires dual column confirmation when using GC/FID.

Accurate boiling point determination for medium and heavy fractions using GC simulated distillation requires columns and phase polymers that are robust enough to withstand high temperatures without significant degradation. Metal columns are a better alternative than fused silica, and the MXT®-1HT SimDist columns are the lowest bleed, highest efficiency columns available, outperforming other metal columns for critical method p…

Rtx-Wax columns are the most inert and efficient PEG columns currently available. The extended operating temperature range allows analysis of compounds having a wide volatility range and ensures low bleed at temperatures as high as 250 °C. Selectivity is comparable to other Carbowax columns for compounds of intermediate to high polarity.

Extend column lifetime. Excellent inertness—obtain lower detection limits for active compounds. Sharper chromatographic peaks by utilizing retention gap technology. Maximum temperature: 360 °C.
