Discussion on Pre-treatment Issues for ICP-MS
Thread Content
As the title suggests, according to the literature, before testing the solution using ICP-MS after the experiment, concentrated nitric acid is added to the solution and it is heated in a microwave oven; however, the specific concentration of the concentrated nitric acid is not mentioned, nor is the heating time in the microwave oven. May I ask, what is the typical concentration of concentrated nitric acid used in such pretreatment? How long does it take to heat in a microwave oven?
For this type of conditional test, the tester must explore and optimize the conditions on their own.
