BASi EC News - July 2009

New EC epsilon™ Software

The latest version of EC epsilon software (v. 2.11) is now available for download here. The software may also be downloaded by non-users as demo software. If the software is opened without the epsilon being connected, all the techniques in the Technique List Box are labeled as "demo. " If a "demo" technique is selected, a Windows dialog box will open to allow the operator to select a data file for that particular technique. The operator can then examine the input parameters and typical output. This also applies for techniques included in optional software packages, if these options have not been purchased.

In addition to various "bug" fixes (discussed in the readme.txt file included with the update and viewed here), new features in this version include:

• The feature, Ohmic potential (iR) compensation, has been added to all potentiostatic techniques. Previously it was only available with CV and LSV.
• Maximum data file length has been increased from 32,000 points to 64,000 points for techniques CV, CPE, DCPA, CP, OP, MCA, and MCCV.
• Converted files for SW and SWSV now have four columns of data: potential, difference current, forward current, and reverse current.
• Scan Rate with CV has been increased from 10 V/s to 25 V/s.

American Chemical Society Fall Meeting

BASi will exhibit in booth 1314 at the 2009 ACS Fall Meeting in Washington, DC. The Exposition will be held in the Washington Convention Center, Halls B-C, Sunday, August 16, 6:00 - 8:30 in the evening; Monday and Tuesday, August 17 and 18, 9 - 5; and Wednesday, August 19, 9 - 2.

KinFitSim: Kinetics Simulation and Fitting Software

KinFitSim is a digital simulation program for homogeneous kinetic chemical reaction mechanisms. The software was developed by Professor Irina Svir as a flexible, yet powerful general-use package that can be used in many applications in teaching and research for photochemistry, organic chemistry, and biochemical investigations. It offers:

• User-friendly, Windows^® interface
• User-specified homogeneous reaction mechanism
• Import photochemical data for fitting
• Automatic parameter optimization for best fit to experimental data
• Three methods of numerical simulation
• Four fitting optimization methods

Tutorials, demo software, publications, and pricing are on the BASi website.

DigiSim Installation Software

Reminder for DigiSim users. If you wish to install the software on a new computer, it is better to download and install from the BASi website rather than from the original disk. The BASi site will have the latest dongle driver which will work with all the following Windows operating systems: Windows 98/ME/NT/2000/XP/Server 2003/Vista (32- bit and 64 bit).

DigiSim Dongle Exchange

Many newer computers do not have parallel ports, thus older parallel keys will not work. These parallel keys can be exchanged for USB keys. Contact BASi for details and pricing.
