Abstract

Quantitation of benzene in gasoline is becoming important due to new federal and state regulations. To meet these regulations an on-line analysis method for benzene in gasoline is needed. It has been shown that NIR is an ideal instrument for on-line analytical measurements. We report in this paper an analysis of benzene in synthetic gasoline with a standard error of prediction of 0.22 wt%. Both principal component analysis and partial least squares chemometric calibration methods were used. Both methods gave the same results for the prediction of the validation sample set.
