OCECgo: A MATLAB Tool for the Sunset Model 4 Instrument

OCECgo is a MATLAB-based software tool for the quantification of uncertainties in the calibration and data analysis of the Sunset Laboratory Model 4 semi-continuous thermal-optical organic/elemental carbon analyzer.

Features

The accompanying submission to the Journal of Visualized Experiments includes the step-by-step procedure for using OCECgo to acquire calibration data, analyze measured data, and compute uncertainties. The OCECgo software includes the following features:

  • Monte Carlo-based analysis of instrument calibration and associated uncertainties:
    • Consideration of uncertainty in the carbon concentration of the external sucrose standard
    • Consideration of uncertainty in the application of sucrose via pipette during calibration
  • Monte Carlo-based analysis of uncertainty in the analysis of OCEC data:
    • Propagation of uncertainty due to calibration and split point estimation
    • Simple and rapid assessment of dominant sources of uncertainty

Documentation

OCECgo includes complete documentation hosted by Read the Docs.
