For sampling, a low-volume or a medium\/high-volume sampling device may be used. Sampling times between 1 h and 24 h are possible. The sampling volume flow rates can range from 1 m\/h to 4 m\/h (&#034;low volume sampler&#034;) or from 10 m\/h to about 90 m\/h (&#034;medium\/high-volume sampler&#034;). In any case, the linear face velocity at the collection filter should range between about 0,5 m\/s and 0,9 m\/s.<\/p>\n<p>The method has been validated for sampling periods up to 24 h. The detection limits for single PAHs and the standard deviations resulting from duplicate measurements are listed.<\/p>\n<p>ISo 16362:2005 describes a sampling and analysis procedure for PAH that involves collection from air onto a filter followed by analysis using high performance liquid chromatography usually with fluorescence detector (FLD). The use of a diode array detector (DAD) is possible. The combination of both detector types is also possible. Total suspended particulate matter is sampled.<\/p>\n<p>Generally, compounds having a boiling point above 430 \u00b0C (vapour pressure less than 10<sup>-9<\/sup> kPa at 25 \u00b0C, e.g. chrysene, benz[<i>a<\/i>]anthracene) can be collected efficiently on the filter at low ambient temperatures (e.g. below 10 \u00b0C). In contrast, at higher temperatures (above 30 \u00b0C, see also ISO 12884<sup>[1]<\/sup>), only PAHs having boiling points above 475 \u00b0C (vapour pressure less than 10<sup>-10<\/sup> kPa at 25 \u00b0C) are determined quantitatively.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Ambient air \u2014 Determination of particle-phase polycyclic aromatic hydrocarbons by high performance liquid chromatography<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/iso\/\"><b>ISO<\/b><\/a><\/td>\n<td>2005-02<\/td>\n<td>34<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":597170,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[202,2634],"product_tag":[],"class_list":{"0":"post-597160","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-13-040-01","7":"product_cat-iso","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/597160","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/597170"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=597160"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=597160"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=597160"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
