    Apr\u00e8s un pr\u00e9traitement appropri\u00e9, l'\u00e9chantillon est inject\u00e9 dans un atomiseur \u00e0 tube de graphite.

Les atomes \u00e0 l'\u00e9tat fondamental de l'\u00e9l\u00e9ment cible absorbent la ligne de r\u00e9sonance \u00e9mise par une lampe \u00e0 cathode creuse en plomb, et l'intensit\u00e9 de l'absorption est proportionnelle \u00e0 la concentration en plomb dans une certaine plage, ce qui permet une analyse quantitative de la teneur en plomb.<\/p>\n

            Method Principle After appropriate pretreatment, the sample is injected into a graphite tube atomizer. Lead ions are dissociated into atomic vapor at high temperatures within the graphite tube. The ground-state atoms of the target element absorb the resonance line emitted by a lead hollow cathode lamp, and the absorption intensity is proportional to the lead […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[75],"tags":[],"class_list":["post-4479","post","type-post","status-publish","format-standard","hentry","category-environment"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/posts\/4479","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/comments?post=4479"}],"version-history":[{"count":0,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/posts\/4479\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/media?parent=4479"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/categories?post=4479"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/tags?post=4479"}],"curies":[{"name":"WP","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
