为解决绿茶市场存在的产地与等级掺假问题，研究人员创新性地将电感耦合等离子体原子发射光谱 (ICP-AES)与反向传播神经网络 (BPNN)相结合，开发出同时鉴别绿茶产地 (准确率92.59%)和等级 (88.89%)的方法，并通过SHAP模型可视化解释关键元素贡献，为食品真实性认证提供新范式。

与电感耦合等离子体光谱 (ICP-AES)、原子吸收 (AAS)和原子荧光 (AFS) 等元素分析技术相比，ICP-MS具有检出限低、动态线性范围宽、干扰少、精密度高 ...

The 7900 ICP-MS and 4200 MP-AES are the most sophisticated, user-friendly elemental analysis technologies available. Newly streamlined operational features also make them ideal for a wider range of ...

AES and ICP-AES are both widely used techniques which rely on similar principles and are usually used to analyze more than five elements in the parts per billion range (ppb). Both techniques are ...

AES typically involves creating plasma from the sample. Several inductively coupled plasma (ICP) techniques can be used either with standard mass spectrometry (ICP-MS)—a popular method for trace ...
