Specific trace impurities determined include non-aromatic hydrocarbons, benzene, toluene and individual C9 and C10 aromatic compounds. C10 or higher non-aromatics, if present, may interfere with the determination of benzene, but it can be determined by UOP Method 543. The lower limit of quantitation for any single component is 1 mg\/kg (mass-ppm). Impurities at concentrations above 500 mg\/kg should be determined by UOP Method 744.<\/p>\n<p><strong>Keywords<\/strong><\/p>\n<p><strong>ICS Code<\/strong><\/p>\n<p>ICS Number Code<\/p>\n<p><strong>DOI:<\/strong><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p><b>UOP931-10 Trace Impurities in Mixed Xylenes by GC<\/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\/astm\/\"><b>ASTM<\/b><\/a><\/td>\n<td>2010<\/td>\n<td>12<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":299980,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2637],"product_tag":[],"class_list":{"0":"post-299973","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-astm","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/299973","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\/299980"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=299973"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=299973"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=299973"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
