This method is for determining total fluorine in liquid hydrocarbons or liquefied petroleum gas (LPG) using the Antek 9000F analyzer. It is applicable to liquid hydrocarbons with fluorine levels of 1 to 500 ng/µL (m/v-ppm) with appropriate calibration standards. Higher concentrations can be analyzed by dilution in a solvent such as isooctane or toluene. The fluorine concentration in LPG can be measured down to 0.5 ng/µL. This method is an alternative to UOP Method 619, which uses the potentially troublesome Wickbold combustion apparatus.
