26、 (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations,

27、governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISOI

28、IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some o

29、f the elements of this part of IS0 16017 may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights.

32、17 gives general guidance for the sampling and analysis of volatile organic compounds (VOCs) in air. It is applicable to ambient, indoor and workplace atmospheres and the assessment of emissions from materials in small- or full-scale test chambers. This part of IS0 16017 is appropriate for a wide ra

33、nge of VOCs, including hydrocarbons, halogenated hydro- carbons, esters, glycol ethers, ketones and alcohols. A number of sorbents ) are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. Very polar compounds will generally require derivatization, ver

34、y low boiling compounds will only be partially retained by the sorbents, depending on ambient temperature, and can only be estimated qualitatively. Semi-volatile compounds will be fully retained by the sorbents, but may only be partially recovered. Compounds for which this part of IS0 16017 has been

35、 tested are given in tables. This part of IS0 16017 may be applicable to compounds not listed, but in these cases it is advisable to use a back-up tube containing the same or a stronger sorbent. This part of IS0 16017 is applicable to the measurement of airborne vapours of VOCs in a concentration ra

36、nge of approximately 0,5 pg/ m3 to 100 mg/m3individual compound. The upper limit of the useful range is set by the sorptive capacity of the sorbent used and by the linear dynamic range of the gas chromatograph column and detector or by the sample-splitting capability of the analytical instrumentatio

37、n used. The sorptive capacity is measured as a breakthrough volume of air, which determines the maximum air volume that shall not be exceeded when sampling. 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 t

38、he sorbent tubes. Artefacts are typically sub-nanogram for well-conditioned Tenax GR and carbonaceous sorbents such as Carbopack/Carbotrap type materials, carbonized molecular sieves and molecular sieves such as Spherocarb, or pure charcoal; at low nanogram levels for Tenax TA and at 5 ng to 50 ng l

39、evels for other porous polymers such as Chromosorbs and Porapaks. Sensitivity is typically limited to 0,5 pg/m3 for IO-litre air samples with this latter group of sorbents because of their inherent high background. The procedure specified in this part of IS0 16017 is applicable to low flowrate perso

It is not applicable to the measurement of instantaneous or short-term fluctuations in concentration. 1) The sorbents listed in annex C and elsewhere in this International Standard are those known to perform as specified under this part of

The tubes shall be sealed according to the requirements of EN 1076:1997, subclause 5.6, or equivalent, e.g. with metal screw-cap fittings with polytetrafluoroethylene (PTFE) seals. 6.3 Sorbent tube unions. Two sorbent tubes may be connected in series during sampling with metal screw-cap

44、f EN 1232 IO or equivalent. The sampling pump shall be in accordance with local safety regulations. 6.6 and sample tube or tube holder, if used. Clips should be provided to hold the sample tube and connecting tubing. Plastic or rubber tubing, about 90 cm long, of appropriate diameter to ensure a lea

45、k-proof fit to both pump Sampling tubes shall not be used with plastic or rubber tubing upstream of the sorbent. The use of such tubing may introduce contaminants or sorbed sampled VOCs. 6.7 Soap-bubble meter or other suitable device for calibrating pump. The flow meter shall be traceably calibrated

46、 to a primary flow standard. NOTE several tens of percent. The use of an uncalibrated integral flow meter for the calibration of pump flowrates may result in systematic errors of 6.8 suitable detector, capable of detecting an injection of 0,5 ng toluene with a signal-to-noise ratio of at least 5 to

47、1. Gas chromatograph, fitted with a flame ionization, photoionization detector, mass spectrometric or other The gas chromatograph shall have a capillary column capable of separating the analytes of interest from other components. 6.9 the desorbed vapours via an inert gas flow into a gas chromatograp

48、h. A typical apparatus contains a mechanism for holding the tubes to be desorbed whilst they are heated and purged simultaneously with inert carrier gas. The desorption temperature and time is adjustable, as is the carrier gas flowrate. The apparatus should also incorporate additional features, such

49、 as automatic sample tube loading, leak testing, and a cold trap in the transfer line to concentrate the desorbed sample (10.2). The desorbed sample, contained in the purge gas, is routed to the gas chromatograph and capillary column via a heated transfer line. 6.10 Injection facility for preparing standards by liquid spiking. A conventional gas chromatographic injection pori may be used for preparing sample tube standards. This can be used in situ, or it can be mounted separately. The carrier gas line to the injector should be retained. The back of the injection port
