import_cv: Import cyclic voltammogram

In mikegerhardt/echem: Importing and manipulating data from Gamry potentiostats

Description

Import a Gamry .dta file from a cyclic voltammetry experiment.

Usage

import_cv(inputfile = file.choose(), cols = c("Vf", "Im"),
  refvoltage = 0.21, earea = 0.07065, multiplier = 1000)

Arguments

inputfile	File to import
cols	Columns to import. Must match the column names given by the Gamry software.
refvoltage	Voltage of the reference electrode used in the experiment. This function will add this value to the measured voltage in the data file.
earea	Electrode area. The default value of 0.0765 is the area of a three millimeter disk, in square centimeters.
multiplier	The function will multiply the current by this after dividing by earea. This defaults to 1000 so that the output current density is in milliamps per square centimeter.

Details

This function should be used to import standard half cell cyclic voltammogram experiments. By default, it assumes you are using a 3mm diameter working electrode and a silver/silver chloride reference electrode. These can be changed in the function call. If you're trying to import a cyclic voltammogram performed on a full cell, use import_cell_cv.

Value

Returns a data frame with the measured current, the measured voltage adjusted by refvoltage, and the current density, calculated by multiplying the measured current by multiplier and dividing by earea.
