ISO 16017-1 Indoor, Ambient and Workplace Air - Sampling of Volatile Organic Compounds by Absorbent Tube/Thermal Desorption/Capillary Gas Chromatography - Part 1: Pump Sample

EUROLAB laboratory provides testing and compliance services within the scope of ISO 16017-1 standard. Developed by the International Standards Organization (ISO), this part of the ISO 16017 standard provides general guidance for sampling and analysis of airborne volatile organic compounds (VOCs). It is applicable to the assessment of emissions from materials in ambient, indoor and workplace environments, and in small or full-scale test rooms.

ISO 16017-1 Indoor, Ambient and Workplace Air - Sampling of Volatile Organic Compounds by Absorbent Tube/Thermal Desorption/Capillary Gas Chromatography - Part 1: Pump Sample

This part of ISO 16017 is suitable for a wide variety of VOCs, including hydrocarbons, halogenated hydrocarbons, esters, glycol ethers, ketones and alcohols. A set of sorbent 1) is recommended for sampling these VOCs, where each sorbent has a different applicability range. Very polar compounds often require derivatization, compounds with very low boiling points are only partially retained by sorbents depending on the ambient temperature and can only be predicted qualitatively.

Semi-volatile compounds will be completely retained by the absorbers, but can only be partially recovered. Compounds for which this part of ISO 16017 has been tested are given in the tables. This part of ISO 16017 may apply to unlisted compounds, but in these cases it is recommended to use a spare tube containing the same or stronger absorbent.

This part of ISO 16017 applies to the measurement of airborne vapors of VOCs in the discrete compound concentration range of about 0,5 mg/m³ to 100 mg/m³.

The upper limit of the useful range is determined by the absorption capacity of the sorbent used and the linear dynamic range of the gas chromatograph column and detector, or the sample separation capacity of the analytical instrumentation used. Absorption capacity is measured as breakthrough air volume, which determines the maximum air volume that should not be exceeded when sampling.

The lower limit of the useful range depends on the noise level of the detector and the empty levels of analyte and/or interfering artifacts in the sorbent tubes. Artifacts are typically sub-nanogram for well-conditioned Tenax GR and Carbopack/Carbotrap-type materials, carbonized molecular sieves and molecular sieves such as Spherocarb, or carbonaceous sorbents such as pure charcoal; At low nanogram levels for Tenax TA and at 5 ng to 50 ng levels for other porous polymers such as Chromosorbs and Porapaks. For 10 liter air samples with this last set of sorbent, the sensitivity is typically limited to 0,5 μg/m3 due to their inherently high background.

The procedure outlined in this part of ISO 16017 applies to low flow personal sampling pumps and gives a time-weighted average result. It does not apply to the measurement of instantaneous or short-term fluctuations in concentration.
