Display EG&G M270 Cyclic Voltammetry data using LabVIEW

[roadchem]

Overview
The Display M270 CV file.VI opens, parses and displays cyclic voltammetry data recorded with EG&G M270 software.  The scan rate is indicated on the front panel. These examples also included the "general file display.vi" which is a much more general means by which to display x-y data.

Description
When the CV file must be saved in ASCII format.  The original M270 software can read binary files and re-save them as ASCII if the default setting is correctly set. The program displays only CV data.  Other data types may be displayed but will require minor modification. A sample CV file (13MAYBC) is included.  The data was collected on a 1.0 mM solution of ferrocene in 0.1 M NBu4PF6 / CH2Cl2 at a 3.0 mm Pt electrode, Ag/AgCl reference electrode, and a Pt wire counter electrode at a scan rate of 50 mV/s.  The potentiostat was a EG&G Model 263A interfaced to a PC via a GPIB interface.  The data shows the expected reversible couple.

The M270 software was developed in the mid-80's for GPIB-interfaced potentiostats which include the EG&G PAR Model 263, 273 and Versastat.  It still functions well for these instruments, and is in use in many labs.
