Description
The analytical process often begins with a question that is not phrased in terms of a chemical analysis. The question could be “Does lead in petrol enter our food supply?” or “Is this water safe to drink?” or “Does emission testing of automobiles reduce air pollution?” A scientist translates such questions into the need for particular measurements. An analytical chemist then must choose or invent a procedure to carry out those measurements, When the analysis is complete, the analyst must translate the results into terms that can be understood by others preferably by the general public. A most important feature of any results is its limitations. What is the statistical uncertainty in reported results? If you took samples in a different manner, would you obtain the same results? Is a tiny amount (a trace) of analyte found in a sample really there or is it contamination? Once all interested parties understand the results and their limitations, then they can draw conclusions and reach decisions. This book provides extensive account of recent developments in the field. Attempts have been made to design a textbook by incorporating important topics that are useful and effective for students.
