Dionex ICS-5000

This used Dionex ICS-5000 is a high-performance ion chromatography system built for laboratories that need precise separation and quantitation of ionic species across a wide range of sample types. The platform is a modular design that can be configured as a single or dual channel system, allowing labs to run two independent analyses simultaneously or dedicate one channel to a high pressure method while the other handles a standard flow application. It integrates pumps, eluent generation, suppression, and detection into a single footprint, which makes it a popular choice for environmental, pharmaceutical, and industrial labs running anion and cation analyses.\n\nThe system supports a broad set of detection options including conductivity, UV-Vis, and amperometric detection, giving analysts flexibility depending on the compound class being studied. Its eluent generation cartridges reduce the need for manual eluent preparation, which helps labs maintain consistent retention times and reduce day to day variability. The dual pump architecture also lends itself well to method development work, where a lab may want to compare gradients or column chemistries without tying up two separate instruments.\n\nBecause it was designed for continuous high throughput operation, this ICS-5000 has typically seen service in quality control, environmental monitoring, or research settings validating drinking water, wastewater, or pharmaceutical excipients. It is being sold used and shows normal signs of prior lab use, but remains a capable platform for any group looking to add ion chromatography capacity without the cost of a new system.
