| Abstract: | A direct method for quantitative determination of trace elements in soil samples by LA-ICP-MS with pressed powders was developed.Indium as internal standard was added into the soil sample and mixed with PTFE as binder,followed pressed powder disc was prepared at a pressure of 200 KN.The homogenization of pressed powder and the relative elemental response were investigated.The proposed method has been applied to the direct analysis of trace elements in solid soil standard reference materials.The analytical results are in good agreement with certified values. |
| Keywords: | LA-ICP-MS Pressed powders Soil Trace element |
