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.
