Following electrothermal atomization, it absorbs the resonance line at 283.3 nm. Within a certain concentration range, the absorbance is proportional to the lead content, and quantification is performed by comparison with the standard series. 2 Scope of Application This method is applicable to the determination of lead in graphite powder. 3 Reference Basis GB\/T 24533-2009 4 Instruments and Reagents 4.1 Instruments and Equipment 4.1.1 Testing Instruments No. Name Quantity Technical Requirement Accessories 1 Graphite Furnace Atomic Absorption Spectrophotometer 1 set \u2014 Lead Hollow-Cathode Lamp 2 Argon 1 cylinder Purity \u226599.99% [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":5062,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[81,36],"tags":[],"class_list":["post-5201","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-petrochemical-and-chemical","category-applications"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/posts\/5201","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/comments?post=5201"}],"version-history":[{"count":1,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/posts\/5201\/revisions"}],"predecessor-version":[{"id":5202,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/posts\/5201\/revisions\/5202"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/media\/5062"}],"wp:attachment":[{"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/media?parent=5201"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/categories?post=5201"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/tags?post=5201"}],"curies":[{"name":"WP","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
