Built with Qt Professional Services
The new Echem Analyst™ software runs data analysis for various experiments in Direct Current (DC) Corrosion, Electrochemical Impedance Spectroscopy (EIS) and Physical Electrochemistry.
Gamry Instruments provides customers hardware and software tools to perform electrochemical research. They reached out to Qt Professional Services to update their existing analysis software package, the Gamry Echem Analyst, which missed important features and only worked on Windows systems.
Gamry had a number of requirements for their revamp of Gamry Echem Analyst, including:
Qt Professional Services reviewed the requirements with Gamry and proposed to rewrite the Gamry Echem Analyst tool using Qt for Python (PySide2) and the open-source Qwt graphics library. Qt for Python allowed for all the operational and graphical aspects of the program to be coded in Python syntax, providing the capability for users to edit or augment their functionality at run-time as needed. Qwt provided the tools to generate scientific plots, as well as the means to tailor their axes, labels, and data points interactively.
Since Qwt is based on QtWidgets and C++, Qt Professional Services used Shiboken, the Python binding generator that is part of the Qt for Python package, to generate a Python wrapper for Qwt. This allowed for direct access to the functionality of Qwt’s C++ classes from the Python scripts of the new Gamry Echem Analyst. Shiboken was also used to create a wrapper around Gamry’s C++ analysis libraries, so their functionality could be directly accessed from the Python scripts.
