ISO 16200的本部分给出了挥发性有机化合物（VOCs）取样和分析的一般指南 在空中。 ISO 16200的本部分适用于广泛的挥发性有机化合物，包括碳氢化合物、卤代烃、， 酯、乙二醇醚、酮和醇。建议使用多种装置和吸附剂进行取样 在这些挥发性有机化合物中，每种吸附剂都有不同的适用范围。 注:经常使用活性椰壳木炭。极性化合物可能需要衍生化；极低空 沸点化合物只能部分被吸附剂保留，只能定性估计。 半挥发性 吸附剂将完全保留化合物，但只能部分回收。 ISO 16200的本部分适用于浓度范围为 约1 mg/m3至1000 mg/m3个体有机物，暴露时间为8小时。 有效范围的上限由所用吸附剂的吸附能力设定，并取决于溶液的稀释 通过气相色谱柱和检测器的线性动态范围或样品分析溶液 所用分析仪器的拆分能力。 有效范围的下限取决于噪声 检测器水平和空白水平上的分析物和/或干扰人工制品在取样装置上或 解吸溶剂。对于活性炭而言，人工制品通常为亚纳克，但芳香族化合物含量更高 在一些批次中发现了碳氢化合物。

This part of ISO 16200 gives general guidance for the sampling and analysis of volatile organic compounds (VOCs) in air. This part of ISO 16200 is applicable to a wide range of VOCs, including hydrocarbons, halogenated hydrocarbons, esters, glycol ethers, ketones and alcohols. A number of devices and sorbents are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. NOTE Activated coconut shell charcoal is frequently used. Very polar compounds may require derivatization; very low boiling compounds will only be partially retained by the sorbents and can only be estimated qualitatively. Semi-volatile compounds will be fully retained by the sorbents, but may only be partially recovered. This part of ISO 16200 is valid for the measurement of airborne vapours of VOCs in a concentration range of approximately 1 mg/m3 to 1000 mg/m3 individual organic for an exposure time of 8 h. The upper limit of the useful range is set by the sorptive capacity of the sorbent used and, subject to dilution of the analysed solution, by the linear dynamic range of the gas chromatograph column and detector or by the sample splitting capability of the analytical instrumentation used. The lower limit of the useful range depends on the noise level of the detector and on blank levels of analyte and/or interfering artefacts on the sampling devices or in the desorption solvent. Artefacts are typically sub-nanogram for activated charcoal, but higher levels of aromatic hydrocarbons have been noted in some batches.
