Superior Chromatographic Performance
• High capacity allows injection of complex matrices without overloading the column while maintaining excellent peak shapes for lower concentration analytes.
• Ultralow hydrophobicity and reduced 150mm column length allow for fast analysis of highly polarizable anions such as perchlorate and iodide with a simple, isocratic eluent.
• Quickly separate disparate concentration ratios (1:1000) of perchlorate in high sulfate matrices using simple, isocratic conditions.
• Separate polythionates such as dithionate, trithionate, and tetrathionate.
• Separate color additives including FD&C Yellow #5, FD&C Yellow #6, FD&C Blue #1, and FD&C Red #40 using a hydroxide gradient. Use with a High-Pressure IC system A high-pressure IC system, such as the Thermo Scientific™ Dionex™ ICS-6000 HPIC system or Thermo Scientific™ Dionex™ Integrion™ HPIC system is required to operate this column under standard conditions.
