10、O 17943:2016-10 3 Expert assistance and specialized laboratories will be required to perform the analyses described in this standard. Existing safety requirements are to be observed. Depending on the objective of the analysis, a check shall be made on a case-by-case basis as to whether and to what e
11、xtent additional conditions will have to be specified. This standard has been prepared by DIN-Normenausschuss Wasserwesen (DIN Standards Committee Water Practice) in collaboration with the Wasserchemische Gesellschaft - Fachgruppe in der Gesellschaft Deutscher Chemiker (Water Chemistry Society - Div
12、ision of the German Chemical Society). It is part of the series Deutsche Einheitsverfahren zur Wasser-, Abwasser- und Schlammuntersuchung (German standard methods for the examination of water, waste water and sludge): Determination of volatile organic compounds in water Method using headspace solid-
13、phase micro-extraction (HS-SPME) followed by gas chromatography-mass spectrometry (GC-MS) (F 41). Standard methods published as DIN Standards are obtainable from Beuth Verlag GmbH, either individually or grouped in volumes. The standard methods included in the loose-leaf publication entitled Deutsch
14、e Einheitsverfahren zur Wasser-, Abwasser- und Schlammuntersuchung will continue to be published by Beuth Verlag GmbH and Wiley-VCH Verlag GmbH b) the scope has been extended to comprise a total of 63 volatile and medium volatile substances, including halogenated hydrocarbons, trihalogenated methane
15、s, gasoline components (such as BTEX, MTBE, and ETBE), naphthalene, 2-ethyl-4-methyl-1,3-dioxolane, and highly odorous substances like geosmin and 2-methylisoborneol; c) the principle of the method has not been changed, but it now includes the option to extend the extraction time of medium volatile
16、substances since this can lead to an increase in the detection sensitivity of these substances, e.g. geosmin; d) the method is now also applicable to the matrix “treated waste water”; e) Clause 4 “Interferences” has been rendered more precise; reference to International Standards on sampling has bee
17、n included, the description of possible interferences when using autosamplers that agitate the sample vials with a circular motion during the extraction process has been improved. f) the performance data of the newly included substances were determined in an international interlaboratory trial carri
18、ed out in June 2013, which also included the matrix “treated waste water”; g) the standard has been editorially revised.

45、uctionVolatile organic compounds (VOCs) are often found in the manufacturing processes of paints, adhesives, petroleum products, pharmaceuticals, and refrigerants. Some are used as gasoline additives, solvents, hydraulic fluids, and dry-cleaning agents. This group of compounds belongs to the group o
46、f anthropogenic chemicals. VOC contamination of water resources is a human-health concern because many are toxic and are known or suspected human carcinogens.For the determination of VOCs, several published procedures are available (see References 4,5,6,7,9,12,13, and 14).EN ISO 17943:2016 (E) DIN E
