Application


  • Measurements of relative distribution constants of vaporized hydrocarbons between air and polydimethylsiloxane via capillary columns for the calculation of headspace hydrocarbon compositions.: This research demonstrates the use of p-Xylene in gas chromatography to measure the distribution constants of hydrocarbons, crucial for accurate environmental and chemical analysis (Kim & Yu, 2020).

  • Mutagenic atmospheres resulting from the photooxidation of aromatic hydrocarbon and NO(x) mixtures.: This article explores the mutagenic potential of atmospheric p-Xylene under photooxidation conditions, providing insights into air quality and health-related impacts (Riedel et al., 2018).
