22、compounds (TVOCEN13999) in the exhaust air of an emission test chamber after application of a low-solvent or solvent-free adhesive as defined in EN 923:2005+A1:2008.

27、 and gas chromatography using MS or MS-FID 3 Principle A sufficient volume of test chamber air is drawn with an appropriate flow through a sorbent tube (or several tubes in series) containing a solid sorbent. Volatile organic compounds (VOC) are retained by the sorbent tube, which is subsequently an

28、alysed in the laboratory. The VOC are desorbed from the sampling tube and transferred by a flow of inert carrier gas into a capillary gas chromatograph coupled to a mass spectrometric detector (MS) and to a flame ionisation detector (FID) or only to a mass spectrometric detector. 4 Reagents and mate

29、rials 4.1 Volatile organic compounds for calibration Compounds of gas chromatographic grade. 4.2 Methanol Methanol of gas chromatographic grade. BS EN 13999-2:2013EN 13999-2:2013 (E) 5 4.3 Sorbent material For general purpose, poly(2,6-diphenyl-p-phenylene oxide, particle size (0,18 to 0,25) mm i.e.

30、 (60 to 80) mesh (Tenax1)TA 1 or equivalent sorbent materials) shall be used. For the determination of very volatile carcinogenic organic compounds (e.g. vinyl chloride), Carbopack X 1)or equivalent sorbent materials as described in EN ISO 16017-1 shall be used. 4.4 Carrier gas Helium, argon or nitr

31、ogen with a purity 99,999 % or better. 5 Apparatus 5.1 Sorbent tubes Sorbent tubes made from stainless steel or glass that can be filled with at least 200 mg of Tenax TA sorbent (4.3) are used. For example, tubes with 6 mm external diameter, 5 mm internal diameter and 90 mm long fulfil the requireme

32、nt and are used in many commercial thermal desorbing devices. It is recommended to use unsilanised glass wool or other suitable mechanism, e.g. stainless steel frit to retain the sorbent in the tube and metal screw caps and polytetrafluoroethylene (PTFE) ferrules for closing the sorbent tube. Carbop

33、ack X (4.3) or equivalent tubes are filled as described in EN ISO 16017-1. 5.2 Sorbent tube unions Two sorbent tubes may be connected in series during sampling with metal screw cap couplings with PTFE ferrules. 5.3 Syringes A precision 10 l liquid syringe readable to 0,1 l. 5.4 Sampling pump The pum

34、p shall fulfil the requirements of EN 1232 or equivalent. 5.5 Tubing PE poly(ethylene) or PTFE tubing of appropriate diameter to ensure a leak-proof fit to both pump and sample tube. Sampling tubes shall not be used with plastic tubing other than PTFE upstream of the sorbent to avoid interference fr

35、om contaminants. 5.6 Flow meter calibrator Bubble meter or other appropriate suitable device for gas flow calibration. 5.7 Gas chromatograph A capillary gas chromatograph coupled to a mass spectrometric detector and to a flame ionisation detector or only to a mass spectrometric detector shall be use

37、3EN 13999-2:2013 (E) 6 5.8 Thermal desorption apparatus Apparatus for two-stage thermal desorption of sorbent tubes and transfer of desorbed vapours via an inert gas flow into a gas chromatograph is required. A typical apparatus contains a mechanism for holding the tubes to be desorbed whilst they a

38、re heated and purged simultaneously with inert carrier gas. The desorption temperature and time is adjustable, as is the carrier gas flow rate. The apparatus may also incorporate additional features, such as automatic sample tube loading, leak testing, and a cold trap or another suitable device to c

39、oncentrate the desorbed sample. The desorbed sample, contained in the purge gas, is routed to the gas chromatograph and capillary column via a heated transfer line. 5.9 Injection facility for preparing standards by liquid spiking Use a commercially available unit for preparation of calibration stand

40、ards or any other device allowing reproducible preparation of calibration standards. 5.10 Emission test chamber An emission test chamber as described in EN 13999-1 or in EN ISO 16000-9 shall be used. 6 Procedure 6.1 Preparation of sampling tubes 6.1.1 Preconditioning Use commercially pre-cleaned sam

41、pling tubes containing Tenax TA or sampling tubes that are preconditioned and filled in the laboratory as described for Tenax TA in this clause. For special purposes such as determination of specific carcinogenic volatile organic compounds as foreseen in EN 13999-1, other sorbent materials as descri

42、bed in EN ISO 16017-1 can be taken. Remove trace impurities of manufactured Tenax TA before using it for VOC sampling. The success of the cleaning procedure is checked by performing analysis of the blank sorbent. Tube blanks are acceptable if no individual interfering artefact peaks exceed 2 ng and

43、if TVOC levels do not exceed 20 ng after subtraction of non-interfering VOC artefacts. NOTE Usually keeping the tubes at a temperature of (320 10) C for at least 3 h using carrier gas flow of 50 ml/min to 100 ml/min is sufficient. Pack one end of the sampling tubes with unsilanised glass wool or sta

44、inless steel gauze. Weigh the appropriate amount of adsorbent. Transfer the adsorbent into the tube e.g. using suction. Prior to storage or conditioning seal the open end of the tube in the same manner as was done with the other end. To maintain the sorption capacity of the sampling tube, use no les

45、s than 200 mg of sorbent per tube. 6.1.2 Conditioning Recondition the pre-cleaned sampling tubes prior to each use at temperature of (320 10) C for 30 min (Tenax TA) under inert carrier gas flow of 50 ml/min to 100 ml/min to remove trace organic volatiles possibly trapped on the tube. Analyse the tu

46、bes, using routine analytical parameters, to ensure that the thermal desorption blank is sufficiently small. If the blank is unacceptable, repeat the conditioning procedure. The tube blank is acceptable if no individual interfering artefact peaks exceed 2 ng and if TVOC levels do not exceed 20 ng af

47、ter subtraction of non-interfering VOC artefacts. If the blank is unacceptable, recondition the tubes by desorbing them for 10 min under a 50 ml/min to 100 ml/min flow rate of inert carrier gas at a BS EN 13999-2:2013EN 13999-2:2013 (E) 7 temperature 20 C higher than that used for analysis and then

48、repeat the analysis. If after repeated conditioning, the blank is still unacceptable, the tubes shall be re-packed. It is recommended to seal the conditioned sorbent tubes with metal screw caps fitted with PTFE ferrules and store the tubes in an emission free container at room temperature. Condition

49、ed sampling tubes should be used within two weeks. Tubes stored for more than two weeks should be reconditioned before sampling. If other sealing material than PTFE/metal is used then the tubes should be used for sampling within 1 week. 6.2 Test chamber air sampling Assemble the sampling line. Prepare the test chamber sampling port as described in EN 13999-1 or EN ISO 16000-9. If the sampling flow rate is determined with a calibrator, start the pump, note and record the sampling flow rate. Connect the sampler to the chamber sampling port,
