The analysis of organometallics samples using an ICP-OES is not a simple proposition as digestion of the sample or dissolution in an adequate solvent is required. Digestion is a lengthy process and loss of analytes and contamination are severe problems. The dissolution method however requires an aromatic solvent, resulting in specific analysis conditions and special pump tubing, which are not easy problems for a typical laboratory to overcome. This Application Note presents the preparation,characterization and optimization of bitumen after emulsion in water. 高性能ICP光譜儀
