Two new chromatography columns, for high molecular weights and for separating basic and polar compounds
GC capillary phase for high molecular weights.
Analyse high molecular weight compounds with Alltech's new Heliflex AT-1ht capillary column line.
These columns are thermally stable to 380C and demonstrate low column bleed at elevated temperatures.
The AT-1ht gives retention times identical to a true dimethyl polysiloxane phase with excellent inertness. Separating basic and polar compounds, Alltech's new Prevail Select C18 HPLC column analyses basic compounds at neutral to alkaline pH.
Separations include highly basic drugs in a neutral pH showing good efficiency and peak symmetry.
Prevail Select C18 highly pure silica and unique bonding chemistry minimise secondary chromatography effects with basic and polar compounds. Benefits include no tailing, high efficiency, and pH stability from 1-10.
Polypropylene vials for ion chromatography.
Eliminate interference associated with glass surfaces.
Use of polypropylene containers is important to avoid the possibilities of interference from metallic ions that can be leached from glass containers under certain sampling conditions.
Alltech offers a broad selection of plastic vials for ion chromatography applications, plus a full selection of glass autosampler vials and accessories.
