The GB/T 23613-2009 standard specifies in detail the content determination method of mg, iron, nickel, aluminum, copper, silver, gold, platinum, iridium, palladium, rhodium, silicon and other elements in osmium powder. The analysis was carried out by Inductance Coupled Plasma Atomic Emission Spectroscopy (AES) method (ICP-AES). The sample was heated dissolved with fuming nitric acid through a distillation bottle with a branch tube. After the osmium vapor was absorbed, the residual liquid was chilled down and bandwidth evaluation was carried out. Finally, the content of each element was determined by ICP-AES. The standard stipulates that the reagents used are analytical purity grade and the water is secondary pure water to ensure the accuracy and Reliability of the test.
