Beschreibung

Allgemeine Beschreibung

p-Xylene-d₁₀ is a deuterated derivative of p-xylene. It has an isotopic purity of 98atom%D. A series of solutions of p-xylene dissolved in the first 12 members of the 4-n-alkyloxy-4′-cyanobiphenyls (NOCB) were prepared. Principal components S^zz and S^xx - S^yy of the second rank orientational ordering matrix of these solutions were determined by deuterium NMR analysis. It is an anthropogenic volatile organic compounds (VOC), which is useful for the formation of secondary organic aerosol (SOA).

Anwendung

p-Xylene-d₁₀ may be used as an internal standard (IS) for GC/MS analysis of volatile organic compounds in the emissions from a landfill.
