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.
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
OCECgo includes complete documentation hosted by Read the Docs.
