Expandability is the keyword for the 700 Series. Extra pumps and detectors can be added as necessary. The standard configuration includes the ECD-700 detector, the EP-700 pump unit, and the ATC-700 temperature control unit.

HPLC-ECD System

  • Maximum flexibility
  • Multiple pumps and detectors
  • Dual electrode
  • Pulse-free pump

ECD-700 Electrochemical Detector

  • Add an ECD to any HPLC system
  • Two cells per detector possible
  • Amperometric or coulometric cells
  • Dual electrode

EP-700 Pump Unit

  • Pulse quenching by on-board computer control
  • No pulse damper necessary
  • Two channel degasser included
  • Gradient control built in

ATC-700 Temperature Controller

  • Provides most stable retention times and detector signals
  • Performs at room temperature due to its ability to both
    heat and cool.

Ultra-High Sensitivity + Expandability For Your Application Development of ECD

Eicom HPLC-ECD systems have established a reputation for reliability, ultra-high sensitivity and stability. Now, the ECD component, ECD-700 is capable of generating different DC applied potentials on two working electrodes in a single cell or two different types of cells, amperomety and coulometry. This expandability will make it easy to transplant the established electrochemical applications from an existing system in order to acquire Eicom’s robust analytical solutions with sensitivity and stability*. The pump component, EP-700 has two on-line degasser lines and carries one or two independent pumps. Thus, it is possible to parallel two different analytical applications on a single 700 system or run an analytical application with a gradient mode. Simply the new Eicom 700 series has a lot of expandability to fulfill your desire to develop new analytical applications.
*Non optimized LC system for the ECD will lower the performance of Eicom products

The 700 system consists of three modules:

Eicom provides this new lineup either as a total system or as separated components. If you would like to add Eicom’s ECD technology to your HPLC system, the new ECD-700 is the right choice for you.
