Full Description

This gas chromatographic method is for determining trace amounts of benzene, toluene, ethylbenzene, p-xylene, m-xylene, and o-xylene in liquefied petroleum gas (LPG), C₂ -C₄, where the specific trace components are sufficiently resolved from the major components. The range of quantitation for each individual aromatic component is 1.0 to 500 mass-ppm.
