Discusson on how different sample preparation tactics can be used to improve analysis precision. For example, how do we customize the rinse solution for specific samples based on the matrix, followed by pretreatment of the samples? How do we implement an extra cleanup step to recondition the spray chamber and nebulizer for certain types of samples? These tricks and troubleshooting techniques are valuable for operators to achieve high-precision analysis for environmental and geological samples using both ICP-OES and ICP-MS.
