XRF element data of fluvial deposits from the Weiße Elster catchment@en

We used stationary XRF spectrometry for analysing elemental composition of bank and streambed samples from Weiße Elster sub-basins (111 grids of 8*8 km). For XRF sample preparation freeze-dried catchment sediments (8 g) were seaved (2mm) to discard the gravel fraction and large organic matter. Further homogenization was undertaken by grinding the samples with a vibratory Retsch mill MM 200. We created uniform pellets by pressing the powdered samples with a carbon-based binding agent in a Vaneox press at 20 t for 2 min. We conducted elemental analyses in a He atmosphere using a Spectro Xepos energy dispersive XRF spectrometer.本研究采用固定式X射线荧光光谱法（XRF）对白埃尔斯特河（Weiße Elster）子流域内111个8km×8km网格的河岸与河床沉积物样品开展元素成分分析。样品制备流程如下：称取8g冻干汇水区沉积物，经2mm筛分以去除砾石组分及大颗粒有机质；随后使用莱驰（Retsch）MM 200振动研磨机对样品进行研磨以实现进一步均质化；再采用碳基粘结剂，在Vaneox压片机中以20吨压力压制粉末样品2分钟，制备得到均匀压片。最终在氦气氛围下，使用Spectro Xepos型能量色散X射线荧光光谱仪完成元素成分分析。
