Dear customer,

Please note that the EI publishing department has moved to a new print supplier for 2021. The option to purchase Hard Copies of our publications has been suspended until the New Year, when we will be making select areas of the catalogue available again.

Scope

This method covers the determination olefin content of hydrocarbon oils. These include crude oils, heavy fuel oils, middle distillates: diesels with and without biodiesel (including any contribution from olefins in biodiesel), gasoline: E5 and E2 gasoline and other hydrocarbon mixtures typically encountered in petroleum refining operations, which are completely soluble in chloroform. The method is for Fourier transform (FT) spectrometers.

The method has not been tested for continuous wave (CW) instruments.
