Product News: Dionex Introduces New UHPLC Columns for Superior and Unique Selectivity

16 Mar 2011

Dionex Corporation continues to provide innovative new U/HPLC reversed-phase columns for speed
and simplicity to achieve required solutions. The best column for any separation is the column with the right selectivity. It simplifies and speeds-up the method for faster analysis.

Acclaim® C30 reversed-phase HPLC columns are suited to a broad range of separations including hydrophobic, long chain, structural isomers (e.g. carotenoids, steroids, and pharmaceuticals), lipids (e.g. phospholipids, omega fatty acids, and cooking oils), and hydrophilic analytes (e.g. water-soluble vitamins). The Acclaim C30 column provides unique selectivity and complements the other high-resolution reversed-phase Acclaim columns.

Acclaim Phenyl-1 columns are designed with high aromatic selectivity and high hydrophobic retention, thus providing unique selectivity for aromatic compounds.

Acclaim RSLC 2.2 μm columns reversed-phase, 2.1 × 250 mm columns provide ultra-high resolution and can be used up to 1200 bar pressure. These columns are designed to accompany the UltiMate® 3000 Rapid Separation LC (RSLC) system and are available in four chemistries: C18, C8, PolarAdvantage (PA) and PolarAdvantage II (PA2).

Acclaim RSLC Carbamate 2.2 μm columns are designed for high resolution and high throughput analysis of carbamates specified in United States Environmental Protection Agency (US EPA) Method 531.2, using LC-postcolumn derivatization-fluorescence or LC-MS methods. Carbamates are widely used as pesticides for food crops worldwide. The new 2.2 μm particle size is designed for use when high sensitivity and ruggedness are required, such as LC/MS.
