Capillary columns, CP-Sil 5/C₁₈ CB for PCB

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.

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.
