UiEChem™ Software

The UiEChem™ software package interfaces with our range of potentiostats and provides a suite of sweep, step and pulse experiments which can be used by the researcher to investigate the oxidation and reduction profiles of electrochemically active materials for a wide range of applications. These include: -

• Sensors
• Biomedical
• Material screening and evaluation
• Electrode reactions and kinetics
• Teaching

The UiEChem™ package includes the common electrochemical techniques: -

• Cyclic and linear voltammetry
• Chronoamperometry
• Chronopotentiometry
• Normal and differential pulse voltammetry
• Square wave voltammetry
• User definable experiments via macro programming

TEMPLATES

A chronoamperometry experiment with multiple pulses can easily be constructed from an experiment template.  The steps can be edited or removed with the need to reformat the whole sequence.  New pulses can be inserted in the sequence.  During each step the user can elect to collect or not to collect data.  Multiple cycles are also available.

DATA TEMPLATES

A series of standard graphics templates are included with the package but the user can construct their own standard graph which can include a mixture of experimental parameter, data tables and plot formats.

AUTOSEQUENCING

Applications which require complex waveforms or automatic sequencing of events are easily handled with the latest version of UiEChem™.

Where a complex experimental protocol is required, for example with a mixture of fast and slow sample rates or multiple repeats or very long time sequences, then the unique AUTOSEQUENCE template allows the user to construct and execute the procedure automatically. This procedure which can involve multiple experiments or logic steps (time delays or loops) is built with the click of the mouse.  The finished sequence can be edited or changed easily without the need to reformat the whole procedure.  The sequence can be saved for recall at a later time.

This graphic shows a sequence of chronoamperomentry experiments where the waveform is the same apart from the final pulse which changes with each step in the sequence.  The sequence executes and stores the data to disk automatically.  With the addition of the LOOP routine the whole sequence is repeated a number of times without the need for a user intervention.

CUSTOM TECHNIQUES

The Windows™ software applications provide a facility to implement custom techniques by programming macro experiments. This facility gives direct control of the advanced PG580 waveform generator and data acquisition features and allows the custom experiment to be displayed on a user defined window template.

STAND ALONE PROGRAMMING

The Windows™ software applications provide a facility to implement standalone programming of the PG581. In this mode the PG581 stores a user defined program which controls the instrument actions and display. The PG581 will execute this user program and display the plot on its graphics screen.
