C<sub>8<\/sub> and lower boiling paraffins and naphthenes are de-termined individually and then summed by carbon number and carbon type. C<sub>9<\/sub> non-aromatics are reported as a composite. The method is not quantitative for C<sub>3<\/sub> and lower molecular weight hydrocarbons due to their volatility. The range of quantitation for each component is 1 to 2000 mass-ppm. The range of quanti-tation for each composite depends upon the number of components in the composite.<\/p>\n<p>An alternative method providing similar information is UOP Method 868, Trace Saturates in High Purity Aromatics by GC. It uses a two-column system to report paraffins and naphthenes by carbon number through C10.<\/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>UOP976-02 Trace C<sub>4<\/sub>-C<sub>9<\/sub> Saturates in High Purity Aromatics 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>2002<\/td>\n<td>11<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":299997,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2637],"product_tag":[],"class_list":{"0":"post-299992","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\/299992","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\/299997"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=299992"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=299992"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=299992"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
