Chromatography Columns

Chromatography columns separate molecules within mixtures during gas or liquid methods. Filled with stationary phase compositions or resins, the prepacked options reduce the preparing time required. The vertical pieces are able to withstand extreme temperatures and pressure fluctuations experienced when the mobile phase is forced through the medium. Meet preparative and analytical laboratory procedures with the chromatography columns to separate dissimilar moving components based on individual polarity, composition, and size.

Capillary columns, CP-Al₂O₃/Na₂SO₄

Capillary columns, CP-Al₂O₃/Na₂SO₄

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.

Solid phase extraction cartridges, Bond Elut™ C1

Solid phase extraction cartridges, Bond Elut™ C1

Supplier: VARIAN

Due to the methyl group and subsequent low carbon load, Bond Elut™ C1 is the least retentive of all alkyl group bonded phases for non-polar compounds. However, due to the extensive end capping of this sorbent to mask polar silanol activity, retention and elution of polar and multi-functional analytes can still be achieved. Typical applications include plasma, urine and aqueous samples.
