元素分析（Elemental Analysis）是一種用于确定物質中化學元素組成及其含量的科學方法。該技術通過定量或定性手段，識别樣品中的碳、氫、氮、硫、氧等基本元素，廣泛應用于材料科學、環境監測、制藥工業和地質研究等領域。
在化學領域，元素分析是化合物結構鑒定的基礎步驟。例如，有機化合物的燃燒法分析（如CHNS分析）通過高溫氧化反應測定碳、氫、氮、硫的含量，其精确度可達±0.3%，該方法被美國材料與試驗協會（ASTM）列為标準檢測程式。材料科學中，X射線熒光光譜（XRF）和電感耦合等離子體質譜（ICP-MS）等技術可檢測金屬合金或半導體材料中的微量元素。
國際純粹與應用化學聯合會（IUPAC）明确指出，元素分析需遵循嚴格的質量控制标準，包括空白試驗、标準物質校準和不确定度評估。環境監測領域則通過該技術檢測土壤重金屬污染或大氣顆粒物成分，相關數據被收錄于美國環境保護署（EPA）的污染物數據庫。
元素分析（Elemental Analysis）是化學和材料科學中的基礎技術，主要用于确定物質中元素的種類和含量。以下是其核心要點：
若需進一步了解具體技術原理或案例，可提供更詳細的問題方向。
