ASTM UOP755-13

Active Standard: Trace Impurities in High Purity Ethyl Benzene by GC

ASTM UOP755

Scope

This method is for determining trace impurities in high purity ethyl benzene by gas chromatography (GC). Specific impurities identified include benzene, toluene, p-xylene, m-xylene, o-xylene, cumene, n-propylbenzene, 1,2-diethylbenzene, 1,3-diethylbenzene, and 1,4-diethylbenzene. Non-aromatics and unidentified C9+ aromatics are determined as composites. Benzene and toluene may not be separated from the non-aromatic impurities by this method but, if required, may be determined individually by UOP Method 543, “Trace Non-Aromatic Hydrocarbons in High-Purity Aromatics by Gas Chromatography.” The lower limit of detection for any single component is 2 mg/kg (massppm) except for p-xylene, which has a lower detection limit of 10 mg/kg.
