This paper investigates the possible techniques for measurement of the extinction coefficient of oils in the near UV. Results show that the best technique, in precision and ease of use, is the unknown thickness method. This method, never proposed up to now as far as we know, allows the use of a standard spectrophotometer. Beer's law is also validated for oils and a simple function is proposed for fitting the extinction coefficient spectra.

Abstract
This paper investigates the possible techniques for measurement of the extinction coefficient of oils in the near UV. Results show that the best technique, in precision and ease of use, is the unknown thickness method. This method, never proposed up to now as far as we know, allows the use of a standard spectrophotometer. Beer's law is also validated for oils and a simple function is proposed for fitting the extinction coefficient spectra.File in questo prodotto:
