APPI(+)-FTICR mass spectrometry coupled to partial least squares with genetic algorithm variable selection for prediction of API gravity and CCR of crude oil and vacuum residues
APPI(+) FT-ICR mass spectra coupled to GA-PLS allowed to predict API gravity and CCR of crude oils. The procedure saving time and it requires little amount of sample. The models GA-PLS were robust and presenting high predictive capacity.
