General Information
Interfacing Electrochemical Equipment to Personal Computers
There are many types of interfaces used for electrochemical workstations. Among the available variety,
we chose to offer 3 different types. The user has the possibility to choose a package, completely as to his
needs or just the hardware part because he wants to use homespun software.

All – in – One: M Lab
The electrochemical workstation M Lab has an interface on board, which is operated by a microcontroller.
The M Lab is coupled to the host computer by a serial (RS 232) cable. The microcontroller controls the
potentiostat, produces the analogue control voltage and collects the data.

RS 232
or

USB - cable

MLab

Main advantages of this system:
User is not bothered with any interfacing.
Programs are simple and easy to use.
Also notebooks can be used.

Main disadvantage:
Serial communication is limited in speed. Max. number of data sets per second: 10

EDAQ E-CORDER Family
The e-corders from eDAQ are fast USB 2.0 - based AD / DA interfaces which come along with data
common collection software as well as with electrochemical software which is best adapted for analytical
chemistry and other tasks which require fast transactions. Besides fast CV, they are able to feed
techniques as pulse amperometry, square-wave-voltammetry, multi-pulse voltammetry and many other
techniques. E-corders are available with different amount of A/D channels and additional I/O channels.
Besides potentiostats, they directly can be connected to a row of smart sensors (“pods”) for measuring
temperature, pressure, conductivity, pH and others more. The hardware offers 16 bit resolution both for
A/D and D/A conversion. EDAQ also offers some small potentiostats as well as a potentiostat specially
designed for handling extremely small currents in the picoamp range.
