手持式XRF（X-ray Fluorescence，X射线荧光）分析仪是一种便携式的、基于X射线原理设计的物质成分检测设备。其工作原理是利用X射线照射样品表面，当样品吸收X射线能量后，原子内部的电子被激发至高能级，随后电子会跃迁回低能级，同时释放出特征X射线（即荧光X射线）。通过检测这些荧光X射线的能量和强度，就可以确定样品中存在哪些元素及其相对含量。

手持式XRF分析仪具有以下特点和应用范围：

1. 便携性：因其体积小、重量轻、电池供电，适合现场快速检测，无需将样品带回实验室。

2. 非破坏性检测：在不破坏样品的情况下就能完成分析，特别适用于艺术品鉴定、考古发掘、环保监测、地质勘探等领域。

3. 广泛应用：在工业领域，广泛应用于金属合金材料识别、矿石品位分析、土壤重金属检测、消费品安全（如RoHS合规性检测）、石油化工产品分析等。

4. 快速准确：通常能在几秒钟内给出常规金属合金的化学成分及牌号信息，极大地提高了生产效率和质量控制水平。
