1、Designation:D666110Standard Practice forField Collection of Organic Compounds from SurfacesUsing Wipe Sampling1This standard is issued under the fixed designation D6661;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last
2、 revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice addresses sampling of organic compounds(i.e.,PCBs,dioxins,many pesticides and similar compounds)from smooth nonpo
3、rous surfaces using a solvent-wetted wipesampling method.Samples are collected in a manner thatpermits the solvent extraction of the organic compound(s)ofinterest from the wipes and subsequent determination using alaboratory analysis technique such as gas chromatography witha suitable detector.This
4、practice is,however,unsuitable for thecollection of volatile organic compounds.1.2 This practice should only be used to collect samples forthe determination of organic compound(s)on a loading basis(e.g.,mass per unit area).It cannot be used to collect samplesfor the determination of organic compound
5、s on a concentrationbasis(e.g.,mass per unit mass).1.3 This wipe sampling practice is not recommended forcollecting samples of organic compounds from rough or poroussurfaces such as upholstery,carpeting,brick,rough concrete,ceiling tiles,and bare wood.It is also not intended for thecollection of dus

11、mmary of Practice4.1 A wipe sample is collected from a smooth nonporoussurface with a solvent-wetted wipe following a specifiedpattern of wiping to ensure complete coverage of an area ofspecified dimensions.The wipe is then extracted and analyzedto detect and quantify(at least semiquantitatively)the
12、 presenceof organic compounds on surfaces.5.Significance and Use5.1 Wipe sampling is typically used by persons involved inhazardous waste site investigations to characterize the arealextent and the level of contamination on walls,floors,equipment,etc.Wipe sampling is also used to determinecompliance
