The sample is atomized in an atomic\u2011absorption flame, and the absorbance is measured at 422.7\u202fnm. Within a certain concentration range, the absorbance is proportional to the calcium content, and quantification is performed by comparison with the standard series. 2 Scope of Application This method is applicable to the determination of calcium in milk powder. 3 Reference Basis GB 5009.92\u20112016, National Food Safety Standard \u2014 Determination of Calcium in Foods 4 Instruments and Reagents 4.1 Instruments and Equipment 4.1.1 Testing Instruments No. Name Quantity Technical Requirement Accessories 1 Flame Atomic Absorption Spectrophotometer 1 set \u2014 [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":5212,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[36,73],"tags":[],"class_list":["post-5211","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-applications","category-food-and-drugs"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/posts\/5211","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=5211"}],"version-history":[{"count":1,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/posts\/5211\/revisions"}],"predecessor-version":[{"id":5213,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/posts\/5211\/revisions\/5213"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/media\/5212"}],"wp:attachment":[{"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/media?parent=5211"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/categories?post=5211"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.pgeneral.com\/ja\/wp-json\/wp\/v2\/tags?post=5211"}],"curies":[{"name":"WP","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
