Hi All, I am trying to prepare wood samples, collected from urban streams, to measure heavy metal concentrations using ICP-MS. Most protocols seem to rely on either a microwave assisted acid digestion or refluxing. I do not have access to an appropriate microwave for acid digestion and have not been able to achieve a complete digestion of wood ash on a hot plate. Does anyone have experience with protocols that work well for acid digestion of wood ash? I would appreciate any suggestions.
