Supplier: VARIAN

CP-Sil 8 CB for amines is a base-deactivated 5% phenyl polydimethylsiloxane column that can be used for a wide range of amines.

Supplier: Thermo Fisher Scientific

Metal-to-metal seal eliminates contamination and gives lower air/water background noise. No need to retighten ferrules, as they expand and contract with the fitting over GC operating temperatures.

Supplier: VARIAN

Ideal as primary or confirmation column.

Supplier: MACHEREY-NAGEL

Special GC phase for the analysis of diethylene glycol.

Supplier: MACHEREY-NAGEL

Special polar GC phase for the analysis of amines.

Supplier: Restek

General purpose columns for pesticides, herbicides, rosin acids, phthalate esters, sterols. The high thermal stability of Rtx®-50 columns makes dual column analysis possible with common phases such as Rtx®-1 or Rtx®-5MS.

Supplier: VARIAN

Guaranteed analysis of FAME cis/trans isomers for complete confidence.

Supplier: Agilent

These columns are recommended for semivolatiles, halogenated compounds, pesticides, herbicides, drugs of abuse, amines, unknown sample screening.

Supplier: Thermo Fisher Scientific

These columns are custom-tailored to analyse dioxins and polychlorinated biphenyls (PCBs). Optimised to meet the requirements of high-resolution GC/MS methods, these columns deliver optimum performance with exceptional stability and very low bleed. These low-polarity columns provide wide coverage of the 17 cogeners with the highest toxicological significance (2,3,7,8-chlorine substituted congeners).

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-Wax 51 for amines is designed for the analysis of C4-C10 amines, diamines and aromatic amines.

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: Restek
