Project Description

Dionex™ Aquion™ Ion Chromatography (IC) System

Compact easy ion chromatography system for isocratic separations of anions or cations using self-regenerated electrolytic suppressors and conductometry detection.

The Dionex Aquion is an integrated single channel ion chromatography system that performs all types of isocratic IC separations. Electrolytic suppression provides high performance ion chromatography of anions and cations with no need to make up regenerant solutions. Each Dionex Aquion system includes a dual-piston isocratic pump, a high-pressure pulse damper, Rheodyne injection valve, and advanced digital conductivity detector with thermal control capabilities. Options: vacuum eluent degas and column heater.

Key Features:

  • Dual-piston pump
  • Electrolytic suppression
  • Digital conductometry detector with temperature control
  • USB interface, “plug-n-play”
  • Optical Eluent Leak Sensor

Benefits:

The integrated system is preconfigured, assembled and tested by the manufacturer, to allow immediate use with the highest efficiency. Increased performance with electrolytic suppression.
Enjoy trouble-free operation of the system with acids and alkalis, thanks to the inert material (PEEK ™) of the internal parts of the system.
Dionex Aquion delivers reliable, reproducible results and saves you time and money.
