Dionex ED50A Electrochemical Detector with LC25 Chromatography Oven for Ion Chromatography

The Dionex ED50A Electrochemical Detector integrates advanced electrochemical detection technologies critical for ion chromatography and molecular diagnostics workflows. It supports three primary detection modes:

• Conductivity Detection: Full-scale range from 0.01 μS to 3000 μS, with temperature compensation of 0.0 to 3.0% per °C, utilizing a variable 8 kHz square wave cell drive.
• DC Amperometry: Current detection range from 50 pA to 300 μA, with ±2.04 V cell drive voltage.
• Integrated Amperometry: Charge range from 50 pC to 200 μC, also operated at ±2.04 V.

This detector measures current responses generated by applied voltages in flow-through electrochemical cells, enabling precise characterization of electroactive species in solution. It is widely adopted in biotechnology and bioprocessing environments for applications such as gene editing, molecular diagnostics, and synthetic biology research due to its sensitivity and versatility.

Paired with the Dionex LC25 Chromatography Oven, this unit provides a tightly controlled temperature environment adjustable from 30 to 45 °C in 1 °C increments. The oven maintains optimal thermal conditions for components including:

• Analytical and guard columns
• Self-Regenerating Suppressor (SRS)
• Conductivity and amperometry cells
• Rheodyne electrically actuated PEEK injection valve

The combined system supports enhanced repeatability and stability in chromatographic separations, essential for biomanufacturing quality control and biomedical engineering research. This robust setup is beneficial for researchers focused on live-cell imaging studies requiring precise ion analysis and fluorescence applications in neuroimaging and cell biology.

Key features:

• Multi-mode electrochemical detection covering conductivity, DC amperometry, and integrated amperometry
• High sensitivity with adjustable voltage and current ranges
• Temperature-controlled chromatography oven for above-ambient sample conditioning
• Automated PEEK injection valve for reproducible sample introduction
• Compatible with Dionex IC20 and DX 500 Ion Chromatography systems

This package is sourced from a working laboratory environment and is in good operational condition. Additional BioLC system components may be available separately to expand bioprocessing or synthetic biology analytical capabilities.

Optimized for chromatography workflows in clinical diagnostics, environmental analysis, and pharmaceutical biotechnology, the Dionex ED50A and LC25 oven form a critical platform for reliable ion detection and bioprocess monitoring.
