x荧光光谱分析法作为一种成熟的现代分析技术,广泛用于冶金生产控制、建筑材料、地质、石油、铜铁、贵重金属、生命科学研究等领域。它对主量元素分析精度很高,能与湿法化学分析相媲美,最轻的元素能分析到原子序数4的铍。用它进行地质样品的多元素测定是比较简单快速的,具有检验灵敏度高、时间短、所需样品量少、对人体辐射小等优点。 As a mature modern analytical technique, x fluorescence spectrometry is widely used in the fields of metallurgical production control, building materials, geology, petroleum, copper and iron, precious metals and life science research. It has a high level of elemental analysis accuracy comparable to wet chemical analysis, and the lightest element can analyze beryllium with an atomic number of 4. Use it for multi-element determination of geological samples is relatively simple and fast, with high sensitivity test, a short time, the required sample amount less, the advantages of small radiation to the human body.
