14.1: Sampling and Statistical Analysis of Data

Aug 15, 2020 Sampling is usually themost difficult step in the entire analytical process of chemical analysis, particu- larly where large quantities of samples (a sample is the subset of the population) to be analysed are concerned.

Chemical analysis Britannica

The main steps that are performed during a chemical analysis are the following: (1) sampling, (2) field sample pretreatment, (3) laboratory treatment, (4) laboratory assay, (5) calculations, and (6) results presentation. Each must be executed correctly in order for the analytical result to be accurate.
