元素分析（Elemental Analysis）是一种用于确定物质中化学元素组成及其含量的科学方法。该技术通过定量或定性手段，识别样品中的碳、氢、氮、硫、氧等基本元素，广泛应用于材料科学、环境监测、制药工业和地质研究等领域。
在化学领域，元素分析是化合物结构鉴定的基础步骤。例如，有机化合物的燃烧法分析（如CHNS分析）通过高温氧化反应测定碳、氢、氮、硫的含量，其精确度可达±0.3%，该方法被美国材料与试验协会（ASTM）列为标准检测程序。材料科学中，X射线荧光光谱（XRF）和电感耦合等离子体质谱（ICP-MS）等技术可检测金属合金或半导体材料中的微量元素。
国际纯粹与应用化学联合会（IUPAC）明确指出，元素分析需遵循严格的质量控制标准，包括空白试验、标准物质校准和不确定度评估。环境监测领域则通过该技术检测土壤重金属污染或大气颗粒物成分，相关数据被收录于美国环境保护署（EPA）的污染物数据库。
元素分析（Elemental Analysis）是化学和材料科学中的基础技术，主要用于确定物质中元素的种类和含量。以下是其核心要点：
