Scientific Software Package SCI for M Lab Electrochemical Workstations

SCI is an extended software package for use with the electrochemical workstation M Lab. It is able to control multiples of cells independently even for complex tasks. SCI includes: Repetitions (cycling) of tasks Task lists piling up to 80 tasks per channel (e.g.: pre - polarisation, triangle sweep , post – polarisation)

Conditioned end of a task, switching over to the next, controlled by 2 conditions out of 4

● end if potential >= (or <=) limit ● end if current >= (or <=) limit ● end if charge >= (or <=) limit ● end if time >= limit value

Two conditions may be connected by either AND or OR. For each task, separate conditions may be chosen. Start with previous potential If you want to start a scan from rest potential, click the check box start condition Halt condition This condition shall meet absolute emerency conditions. If the condition is met, the cell is switched off immediately. Trigger A conditioned trigger can be used to switch external devices. Output 0V/5V. Currently the second channel is not available when the external trigger is used. Direct data export to MS Excel (.XLS) now from the data panel Separated data storage for chained tasks using automated name extensions

New Scope functions The scope screen is a sub - function of the cell check mode, allowing to trace potential and current at the settings of cell check to analyse possible cell problems, or just to estimate the optimal time settings for a transient measurement. Software Watchdog Option watchdog controls the data flow. This option is helpful for longtime polarization, where a break in the data flow may happen. The software watchdog is now part of the SCI software package. Hardware Watchdog The hardware watchdog watches the potential of the electrodes independent of the software. If the potential exceeds a preset limit it immediately disconnects the counter electrode. This option is valuable for long-term polarization, when e.g. a fading or disconnection in the electrolyte bridge sets the potential control out of operation. Other Features XY-plots following European or American plot style Second data sets can be added to the plot by concatenation (addition of the second data set to the first one), or as an overlay using another colour. Tafel lines are calculated automatically, manual correction is possible. From the Tafel lines, the corrosion rate can be displayed (the set of metals used for this calculation is editable). Potentials can be referred to other reference electrodes. Currents can be plotted as current densities. Both averaging and median filtering can be applied to the data. The data storage follows GLP. You decide whether to save raw data only or – after the raw data have been saved, also the smoothed or filtered data. Free trials of the software can be downloaded from our website:
