Elemental analysis - Wikipedia
Elemental analysis is a process where a sample of some material (e.g., soil, waste or drinking water, bodily fluids, minerals, chemical compounds) is analyzed for its elemental and sometimes isotopic composition.
元素分析 - 百度百科
元素分析是研究有机化合物中元素组成的化学分析方法。 分为定性、定量两种。 前者用于鉴定有机化合物中含有哪些元素； 后者用于测定有机化合物中这些元素的百分含量。 例如，被测物质在特殊仪器中燃烧后，可定量地测定成 二氧化碳 形态的碳、成水形态的氢、成单体形态或 氮氧化物 形态的氮和成 二氧化硫 形态的硫等。 [1] 利用化学反应测定化合物元素组成和百分含量的方法。 前者称为元素定性分析，后者称为元素定量分析。 进行完整的元素分析后，可以计算出化合 …
Elemental Analysis - an overview | ScienceDirect Topics
Elemental analysis (EA) is an analytical technique applied in chemistry to determine the elemental composition of chemical compounds and their composites. Through this method, it can be determined which elements are present and how many percent by mass of each chemical element is contained in the tested substance to establish the empirical formula.
