VF-17ms is a 50% phenyl, 50% dimethylpolysiloxane, medium polarity, low bleed column for increased sensitivity, accuracy and instrument uptime.

Supplier: VARIAN

Fluorescence cuvettes designed for UV/visible analysis in routine applications of molecular spectroscopy.

Supplier: VARIAN

A medium polarity sorbent with many uses, Bond Elut™ CN-E is ideal for applications in which extremely non-polar compounds would be irreversibly retained on high carbon load sorbents such as C₈ and C₁₈. This endcapped version of the cyano sorbent is best utilised when extracting analytes from an aqueous matrix.

Supplier: VARIAN

The Polaris C18-A phase is specially designed for high-throughput and LC/MS analysis of polar analytes in drug discovery, drug metabolism, and AR&D areas.

Supplier: VARIAN

Bond Elut CN-U is ideally suited for the extraction of polar compounds from a nonpolar matrix, such as hexane or oils. It is suitable for very polar analytes that may be irreversibly retained on SI or Diol (2OH) SPE phases.

Les colonnes de perméation sur gel (GPC) classiques offrent une haute résolution sur une plage précise de poids moléculaire. La partie linéaire de la courbe d'étalonnage, où la pente est la moins marquée, définit la région de poids moléculaire où la résolution sera optimale.

Pursuit™XRs Ultra UPS 2,8 columns are ultra-purity silica based columns.

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.

Supplier: VARIAN

These Polaris™ phases have rapid high resolution separations based on ultra pure silica to which alkyl chains and polar modifications are attached.

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

The CP-Chirasil Val columns are designed for the separation of optically active compounds, especially amino acids. They have lower bleed levels than other phases with a Tmax of 200 °C, isothermally and programmed.
