Project Description

Dionex™ ICS-4000 Integrated Capillary HPIC™ System

Integrated, ready-to-use ultra-high pressure capillary Ion Chromatography system (HPIC ™) Dionex ™ ICS-4000 for routine applications.

Dionex ICS-4000 HPIC provides a high sensitivity analysis of valuable samples that are available only in trace amounts. At the same time, the system ensures low cost of analysis due to microliter flows of eluent. The system is also indispensable when working with samples that create toxic waste during analysis, and when operating the system in an autonomous mode, when the operator does not maintain the instrument for a long time.

The Dionex ICS-4000 capillary HPIC™ system delivers best-in-class sensitivity, from routine analyses to your most demanding application challenges. The high-pressure capability brings a new level of resolution and speed to dedicated capillary ion chromatography, while integrated design of the Dionex ICS-4000 simplifies your workflow and increases your analytical efficiency and productivity.

Special features:

  • Always ready. Quick start with minimum time, since the system is always on.
  • Extending the lifetime of the system due to the absence of the need for constant on / off, which pose the risk of damage.
  • Excellent control and reproducibility for isocratic and gradient elution up to 200 mM acid or base eluents.
  • Stable chromatographic characteristics
  • Increased sensitivity due to the use of capillary columns for samples of limited volume.
  • Extremely low eluent consumption – one eluent generator cartridge is designed for 18 months of continuous operation (24 hours a day, 7 days a week).
  • Acceleration of analysis due to the use of highly efficient capillary columns, which allow working at fast flows and pressures up to 5000 psi (35 MPa) (up to 2 times faster when using Dionex ™ IonPac ™ Fast IC columns)

Detector Choice:

  • CD Conductivity Detector
  • QD Charge Detector: Complementary detection mode for weakly-dissociated species—can be configured with a CD for peak purity and identification
  • ED Electrochemical detector: sensitive and selective detection of sugars, cyanide, azide, and biogenic amines
