​HPLC-ECD System

700 Series

> Maximum flexibility                       > Dual electrode

> Multiple pumps and detectors     > Pulse-free pump

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 equipped with one amperometric cell, the EP-700 pump unit with one microflow pump installed, and the ATC-700 temperature control unit, The pump unit also has a two channel solvent degasser built in.


ECD-700 Electrochemical Detector

> Add an ECD to any HPLC system

> Two cells per detector possible

> Amperometric or coulometric cells

> Dual electrode


Eicom's ECD-700 electrochemical detector offers superior stability and sensitivity.It relies on the same proven detector cell that's in the HTEC-510. Refer to the previous page for more information. When the standard amperometric cell is fitted with the optional dual electrode, the ECD-700 can monitor two voltages at the same time. A second amperometric and coulometric cell can be added to the unit at any time.

Standard Features

  • Superior sensitivity and stability of Eicom’s electrochemical detector technology.

  • Easy to maintain.

  • Maximized up-time.

  • One amperometric electrochemical detector cell with a constant voltage configuration using the same type of flow cell as the HTEC-510.

  • Available materials of working electrode; graphite, pure graphite, glassy carbon, platinum, gold, silver.

  • Easy access to the working electrode.

EP-700 Pump Unit With Pulse-Free Mode

> Pulse quenching by computer control

> No pulse damper necessary

> Two channel degasser included

> Gradient control built in

Revolutionary pump design effectively quenches flow pulses. Cumbersome pulse damper units are no longer a necessity.

The adaptive algorithm minimizes pressure fluctuations by continually adjusting the piston velocity. Each EP-700 unit holds up to

two pumps, and there are two types to choose from, high flow or micro flow. The standard EP-700 unit comes with one microflow

pump installed.

NO More Pulse Dampers Means

> smaller volume between column and pump

> repid pressure response after starting the pump

> more accurate gradients



ATC-700 Temperature Controller

Temperature control provides the most stable retention times and detector signals.The ATC-700 performs this function even at room temperature due to its ability to both heat and cool.
