The measurements are performed in real time. The guideline deals with the principles of the method and explains the calibration, use and maintenance of the measuring instrument. This method is also suitable for characterising test aerosols. The method is applicable for particles in the size range of about 7 nm to about 10 \u00b5m and in the number concentration range of about 200 cm-3 to about 2&#215;107 cm-3.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Measurement of particles in ambient air &#8211; Determination of the particle number concentration and number size distribution of aerosols &#8211; Electrical Low Pressure Impactor (ELPI)<\/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\/din\/\"><b>DIN<\/b><\/a><\/td>\n<td>2012-12<\/td>\n<td>28<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":553697,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[203,2635],"product_tag":[],"class_list":{"0":"post-553683","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-13-040-20","7":"product_cat-din","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\/553683","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\/553697"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=553683"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=553683"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=553683"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
