Sample Preparation
Sample preparation refers to the different ways or methods in which a sample is treated before analysis.
Sample preparation can be both time-consuming and a main source of errors, having a major impact on the result of any analytical method and the purity of the sample prior to further analysis. So choosing the proper sample preparation technique is critical and must be selected to ensure a reliable downstream analysis.
