Method A is not applicable to samples containing compounds that absorb radiation at 220 nm and that are not extracted by diethyl ether, e.g. alkylphenolethoxylates. Method B may be used with samples that contain single or mixed compounds.<\/p>\n<blockquote>\n<p>NOTE The titles of the publications referred to in this Section are listed on the inside back cover.<\/p>\n<\/blockquote>\n<p>Spectrometric and high-performance liquid chromatographic methods.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Analysis of formulated detergents &#8211; Quantitative test methods &#8211; Methods for determination of short-chain alkylbenzenesulphonates content<\/b><\/p>\n<table class=\"shortdes-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\/bsi\/\"><b>BSI<\/b><\/a><\/td>\n<td>1989<\/td>\n<td>10<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":289037,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[1030,2641],"product_tag":[],"class_list":{"0":"post-289030","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-71-100-40","7":"product_cat-bsi","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\/289030","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\/289037"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=289030"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=289030"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=289030"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
