CEI Capillary Electrophoresis with C4D and UV Detection
  • Economical, Easy to use
  • Flexible and upgradable
  • Choice of detectors


The CEI is an easy to use, economical capillary electrophoresis (CE) instrument perfect for research and teaching. It has an innovative modular design where each module is easily accessible and interchangeable. This makes maintenance a lot easier and it allows for a flexible, upgradable system.

The instrument is equipped with a touchscreen panel. The simple user interface makes it easy to set up and launch analysis. The data is collected and analysed in PowerChrom software.

The instrument allows for both hydrodynamic or electrokinetic sample injection. The capillary is housed in a cartridge and the temperature is regulated using a flow of air. The CE instrument can be connected to other instruments (MS, LC or ICP) using an optional external detector cartridge.

It can be ordered with both contactless conductivity (C4D) and UV detectors, C4D detector only, or UV detector only.

The instrument can be set up in its simplest configuration for a quick analysis and as an excellent teaching and training tool for capillary electrophoresis. It can be upgraded to a semi-automatic or automatic configuration with the optional automated sample carrousel.

The instrument has been used in a wide range of applications, including:

  • Food and beverage: quality control, food safety, oenology…
  • Environmental: analysis of water, soil, air…
  • Pharmaceutical: counterfeit drugs, quality control, chirality
  • Medical: screening and diagnosis
