Semi-volatile organic compounds (SVOCs), partitioned between particulates and vapours of an aerosol, require special attention. The toxicological effects caused by the inhalation of such aerosols may depend on the concentration and in which phase the organic compounds are found. A personal denuder-gas-particle separation aerosol sampler was developed to provide information about the partitioning of aerosols from organic compounds. The sampler was tested in a series of controlled laboratory experiments, which confirmed the capability and accuracy of the sampler to measure gas-particle mixtures. An average difference of 14.8 ± 4.8% was found between sampler and reference laboratory instruments. The obtained results showed that our sampler enables a more accurate measurement of the SVOC aerosols' gas-particle fractionation, compared with that of conventional samplers.
半挥发性有机化合物（SVOCs）分配在气溶胶的颗粒物和蒸气之间，需要特别关注。吸入这种气溶胶引起的毒理学效应可能取决于有机化合物的浓度和存在的相态。开发了一种个人冲击式气体-颗粒物分离气溶胶采样器，以提供有关有机化合物气溶胶分配的信息。该采样器在一系列受控实验室实验中进行了测试，这些实验证实了采样器测量气-颗粒物混合物的能力和准确性。采样器和参考实验室仪器之间的平均差异为 14.8±4.8%。所得结果表明，与传统采样器相比，我们的采样器能够更准确地测量 SVOC 气溶胶的气-颗粒物分馏。
