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, amperometry 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.

Electrochemical Detector, ECD-700

Standard Features

  • Superior sensitivity and stability of Eicom’s electrochemical detector technology.
  • Easy to maintain.
  • Maximized up-time.
  • One amperometirc electrochemical detector cell with a constant voltage configuration using the same type of flow cell as the HTEC-500.
  • Available materials of working electrode; graphite, pure graphite, glassy carbon, platinum, gold, silver.
  • Easy access to the working electrode.

    Available Options

    • The temperature of the electrochemical flow cell can be regulated using model ATC-700. If you require the best performance of the ECD-700, please use the ECD-700 with the ATC-700.
    • Switches to dual working electrodes without changing the standard amperometric cell with a common reference and counter electrode without changing circuit boards.
    • Either additional one amperometric cell with a single working electrode or one coulometric cell with a single working electrode. This option requires an additional circuit board.

    Please consult with us concerning your intended application for the electrochemical detector and your current LC system. Some of the ECD-700’s excellent performance may be lost when used with LC systems not optimized for the ECD-700. To obtain the best stability of the Eicom electrochemical detector, consider setting up with the ATC-700.

    The EP-700 is an HPLC Pump System. It has ultra-high sensitivity, superior stability and adapts to various purposes. From Microdialysis Analysis with a laboratory animal to general analysis.

    The EP-700 is one of the devices that comprises the HPLC Electrochemical Detection system model. It delivers the highest performance system architecture along with the Eicom Electrochemical Detector (ECD) ECD-700 and Temperature Controller ATC-700.

    It has a high sensitivity liquid delivery pump, and degasser. In the EP-700 two different pumps may be mounted. The micro-flow rate pump, or the high-flow rate pump. The EPC-500 can control each pump independently or it can use both pumps to create a high pressure gradient. The pump in the EP-700 has self-learning pulsating flow control which ensures stable liquid delivery.

    The EP-700 is inert with non-metallic parts inside. This creates a superior environment for maintaining a low and stable signal from an electrochemical detector.
