ASTM UOP975-01
Withdrawn Standard: Fluorine in Liquid Hydrocarbons and LPG by Oxidative Combustion with Ion-Selective Electrode Detection
ASTM UOP975
Scope
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.
