Elemental analysis of wood or pulp

Determining the content of S, Na, K, Ca, Fe, Cu, Mg, Mn, Si, and P in a wood or pulp powder sample. The sample is microwave-digested using a solution of HF, HNO₃, and HCl before the analysis. The elements are then detected using the ICP-MS technique. Results are provided as milligrams per kilogram of the sample material.
