Distillate Solutions

Here are some examples of some of the solutions we have provided for distillate measurements.

Typical online PLS analysis of the 10% distillation temperature (10%). The plot shows Raman predicted values vs. the measured laboratory values. The standard error of prediction for the PLS model with outliers removed was 2.06.

A histogram of the distribution of differences between the laboratory and Raman predictions for an independent validation set of spectra that are not included in the PLS model. The standard error of prediction for the validation set (543 samples) with 1 outliers removed was 2.44.

Typical online PLS analysis of the 50% distillation temperature (50%). The plot shows Raman predicted values vs. the measured laboratory values. The standard error of prediction for the PLS model with outliers removed was 1.81.

A histogram of the distribution of differences between the laboratory and Raman predictions for an independent validation set of spectra that are not included in the PLS model. The standard error of prediction for the validation set (543 samples) with 2 outliers removed was 2.34.

Typical online PLS analysis of the 90% distillation temperature (90%). The plot shows Raman predicted values vs. the measured laboratory values. The standard error of prediction for the PLS model with outliers removed was 1.63.

A histogram of the distribution of differences between the laboratory and Raman predictions for an independent validation set of spectra that are not included in the PLS model. The standard error of prediction for the validation set (543 samples) with 4 outliers removed was 1.95.

Typical online PLS analysis of the drivability index (DI). The plot shows Raman predicted values vs. the measured laboratory values. The standard error of prediction for the PLS model with outliers removed was 8.17.
