scope:

This method is for determining trace impurities in, and the purity of, high-purity ethylbenzene by gas-liquid chromatography. Specific impurities identified include non-aromatic hydrocarbons, benzene, toluene, xylenes, cumene, n-butylbenzene and diethylbenzene isomers. C10 or higher nonaromatics, if present, may interfere with the determination of benzene. If required, benzene can be determined individually by UOP Method 543. The lower limit of detection for any single component is 2 mass-ppm except for p-xylene, which has a lower detection limit of 100 mass-ppm.
