1957 Results for: "GC Columns"

Supplier: Thermo Fisher Scientific

Chemically altered tubing surface reduces tailing and eliminates the need for column priming.

Supplier: Restek

MXT®-1301 Siltek®-treated stainless steel columns are general purpose columns for residual solvents, alcohols, oxygenates, and volatile organic compounds.

Supplier: MACHEREY-NAGEL

Medium polar silarylene GC phase with low bleeding.

Supplier: VARIAN

CP-Sil 88 columns have high selectivity towards positional and geometric isomers for ease-of-use.

Supplier: VARIAN

The Select Silanes column is a stabilized trifluoropropyl-methyl polysiloxane phase optimized for silanes determination. The Select Silanes column has a very thick film, resulting in high capacity and retention for highly volatile silanes.

Supplier: Thermo Fisher Scientific

Application-specific columns for blood alcohol analysis.

Supplier: Thermo Fisher Scientific

This low-bleed, stable column produces consistent results.

Supplier: VARIAN

The CP-Select 624 CB is a highly reproducible version of the popular 624 phase and has 2-3 times lower bleed than conventional columns.

Supplier: VARIAN

CP-Sil 8 CB delivers a linear column response down to femtogram levels.

Supplier: Thermo Fisher Scientific

Optimised for linear and quantitative analysis of polar unsaturated hydrocarbons.

Supplier: VARIAN

CP-TAP CB is available in special fused silica for maximum column strength at temperatures up to 370 °C, or UltiMetal capillary for the ultimate robustness.

Supplier: VARIAN

The CP-Si™l line consists of a range of stationary phases which are based on a polysiloxane backbone. Functional groups are added to the polymer to introduce selectivity. Each polymer used for the CP-Sil line is manufactured in-house and is optimised to obtain highest degree of reproducibility.

Supplier: Thermo Fisher Scientific

These columns give greater stability and inertness at elevated temperatures and when working with highly active compounds. They provide greater robustness under increased stress.

Supplier: VARIAN

The Select FAME column is tuned for optimal cis-trans separations of FAMEs, especially C₁₈ isomers.

Supplier: Restek

These application-specific columns for blood alcohol analysis baseline separate all critical compounds - including ethanol, methanol, acetone, tert-butanol, acetaldehyde, isopropanol, and n-propanol - in less than two minutes.

Supplier: Thermo Fisher Scientific

These columns are designed to perform specific EPA methodologies. These low-bleed and temperature-stable columns have been designed, manufactured and tested to provide consistent, reliable results from run-to-run and batch-to-batch.

Supplier: MACHEREY-NAGEL

Nonpolar silarylene GC phase with low bleeding.

Supplier: Thermo Fisher Scientific

These non polar, metal columns allow you to work at temperatures up to 430 °C with no compromise in performance when analysing highly active and aggressive compounds.

Supplier: Thermo Fisher Scientific

These columns are designed for use in carbon neutral fuels development applications.

Supplier: Restek

These fused silica columns have midpolarity Crossbond® phase manufactured for column to column reproducibility suited for validated methods.

Supplier: VARIAN

The CP-Sil 88 column has a very high polarity and a specific selectivity for dioxins and dibenzofuran separations.

Supplier: VARIAN

Ideal as primary or confirmation column.

Supplier: MACHEREY-NAGEL

Special polar GC phase for the analysis of amines.

Supplier: MACHEREY-NAGEL

Medium polar silarylene GC phase with low bleeding.

Supplier: VARIAN

CP-Al₂O₃/Na₂SO₄ is an aluminum oxide PLOT column that offers high selectivity for separating ppm levels of C₁ to C₅ hydrocarbons in a main stream of C₁ to C₅ hydrocarbons. The Na₂SO₄ deactivation salt provides a polar Al₂O₃ surface, so that unsaturated compounds such as ethylene and acetylene are retained longer. These columns analyse more compounds in a single run than packed columns, while still delivering higher resolution and faster analysis times. When compared to liquid stationary phases, CP-Al₂O₃ provides increased selectivity and allows all C₁ to C₅ hydrocarbon isomers to be separated. CP-Al₂O₃ operates without the need for sub-ambient cooling.

Supplier: VARIAN

Ideal as a confirmation column for reliable results.

Supplier: MACHEREY-NAGEL

Special GC phase for the analysis of volatile halogenated hydrocarbons.

Supplier: VARIAN

CP-Sil PONA CB delivers accurate analysis of paraffins, olefins, naphthalenes and aromatics in complex hydrocarbon mixtures.

Supplier: VARIAN

These columns are specially designed for the determination of trace levels of pesticide residue.

Supplier: VARIAN

CP-Sil 5/C₁₈ CB for PCB has a lower polarity than 100% polydimethylsiloxane due to its C₁₈ substitutions. Due to the absence of cyano groups it provides high signal-to-noise ratios for ECD detectors.
