Dionex Introduces New UHPLC Columns for Superior and Unique Selectivity

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.
