一、XRF实验室，什么是XRF实验室？
X射线衍射实验室，一个基本的物理实验室，做X射线衍射用的
二、xrf检测用来做什么？
XRF测试的全称为X射线荧光光谱仪。XRF测试支持两种分析方式:定性分析和定量分析，定性分析的物理基础就是莫塞莱定律，通过不同元素的特征X荧光找到对应元素；定量分析是将未知样的荧光强度与用来建立校正曲线的标准样品的荧光强度和相对应的浓度建立相应关系，以此求得未知样的浓度。
三、xrd和xrf的区别？
1. XRD和XRF有明显的区别。2. XRD（X射线衍射）是一种通过射入物质的X射线，观察其衍射图样来分析物质晶体结构的技术。它可以确定晶体的晶格参数、晶体结构和晶体学性质等。而XRF（X射线荧光）是一种通过射入物质的X射线，测量其产生的荧光辐射来分析物质成分的技术。它可以确定物质中元素的种类和含量等。3. XRD和XRF在原理和应用上有所不同。XRD主要用于研究物质的晶体结构，可以提供更详细的晶体学信息；而XRF主要用于分析物质的成分，可以提供更全面的元素信息。此外，XRD需要样品具有一定的晶体性质，而XRF对样品的要求相对较低，可以对非晶体样品进行分析。因此，根据具体的研究目的和需求，选择适合的技术进行分析是非常重要的。
四、XRf是什么意思？
XRF:X射线荧光光谱分析(X Ray Fluorescence)
人们通常把X射线照射在物质上而产生的次级X射线叫X射线荧光（X—Ray Fluorescence），而把用来照射的X射线叫原级X射线。所以X射线荧光仍是X射线。
X射线是电磁波谱中的某特定波长范围内的电磁波，其特性通常用能量（单位：千电子伏特，keV）和波长（单位：nm）描述。
X射线荧光是原子内产生变化所致的现象。一个稳定的原子结构由原子核及核外电子组成。其核外电子都以各自特有的能量在各自的固定轨道上运行，内层电子（如K层）在足够能量的X射线照射下脱离原子的束缚，释放出来，电子的逐放会导致该电子壳层出现相应当电子空位。这时处于高能量电子壳层的电子（如：L层）会跃迁到该低能量电子壳层来填补相应当电子空位。由于不同电子壳层之间存在着能量差距，这些能量上的差以二次X射线的形式释放出来，不同的元素所释放出来的二次X射线具有特定的能量特性。这一个过程就是我们所说的X射线荧光（XRF）。
五、ROHSEDX跟XRF测试的异同？
edx是能谱即能量色散X射线光谱仪。EDX是借助于分析试样发出的元素特征X射线波长和强度实现的， 根据波长测定试样所含的元素，根据强度测定元素的相对含量。
xrf是波谱即波长色散X射线光谱仪。能谱可以用来做rosh 检测,波谱可以用来做成份分析了。
六、xrf检测是什么意思？
xrf检测指的是X射线荧光光谱仪，可以快速同时对多元素进行测定的仪器。在X射线激发下，被测元素原子的内层电子发生能级跃迁而发出次级X射线（X-荧光）。
