SI-traceable purity assignment of volatile material

Jan 27, 2022 · Ethylbenzene, a typical volatile organic compound, has been widely studied in environmental science areas such as water and gasoline , focusing on the determination at the trace level in the matrix. For the purity assessment of volatile organic compounds, Saito [ 19 ] developed a qNMR method to determine chloroethylene, with the sampling

XAD-2 resin has a higher collection efficiency for volatile PAHs than PUF, as well as a higher retention efficiency. However, PUF cartridges are easier to handle in the field and maintain better flow characteristics during sampling. Likewise, PUF has demonstrated its capability in sampling organochlorine pesticides and polychlorinated biphenyls.

Preparation and performance features of wristband samplers

Jul 26, 2017 · The objectives of this study are: (1) to demonstrate that when the wristband is properly prepared it provides a simple, chemically clean foundation for quantitative organic chemical monitoring; (2) to assess the transport and storage stability of captured chemicals in the wristband, and (3) to estimate wristband–air partitioning coefficients

Volatile organic compounds emission inventory of organic

Jan 01, 2022 · 1. Introduction. Volatile organic compounds (VOCs) play key roles in the formation of atmospheric secondary organic aerosols (SOA). They also act as precursors of ground-level ozone (O 3) and fine particulate matter 2.5 (PM 2.5), which negatively affect human health as well as ecological and socio-economic processes (Kamal et al., 2016; Dai et al., 2017; Mozaffar et al., 2020).
