Summary:An overview of some typical specifications for catalyst poisoners in polymer-grade hydrocarbons is given in Table I. Mass spectrometry (MS) is hardly used in petrochemical QC laboratories, which is primarily because of its apparent complexity and higher cost-of-ownership. Straight full-scan mode proved to be less appropriate for target analysis, which is predominately due to the low molecular weight of the target compounds, and means having to include highly interfering masses such as m/z =18 (water), 28 (nitrogen) and 32 (oxygen) in the scan range.
