ABSTRACT:
The present invention is a method to distinguish and measure normal paraffins, isoparaffins, and naphthenes in a saturated hydrocarbon mixture. The method includes the step of field-ionizing hydrocarbon mixture; separating the normal paraffins, isoparaffins and naphthenes as a separate saturates class; and detecting the normal paraffins as molecular ions, naphthenes as molecular ions, and isoparaffins as fragment ions.
