Analytical chemistry basic tools

Finally, we cannot end a chapter on the basic tools of analytical chemistry without mentioning the laboratory notebook. Your laboratory notebook is your most important tool when working in the lab, providing a complete record of all your work. If kept properly, you should be able to look back at your laboratory notebook several years from now and reconstruct the experiments on which you worked. 

There are a few basic numerical and experimental tools with which you must be familiar. Fundamental measurements in analytical chemistry, such as mass and volume, use base SI units, such as the kilogram (kg) and the liter (L). Other units, such as power, are defined in terms of these base units. When reporting measurements, we must be careful to include only those digits that are significant and to maintain the uncertainty implied by these significant figures when transforming measurements into results. 

The textbook s organization can be divided into four parts. Chapters 1-3 serve as an introduction, providing an overview of analytical chemistry (Chapter 1) a review of the basic tools of analytical chemistry, including significant figures, units, and stoichiometry (Chapter 2) and an introduction to the terminology used by analytical chemists (Chapter 3). Familiarity with the material in these chapters is assumed throughout the remainder of the text. 

An introductory manual that explains the basic concepts of chemistry behind scientific analytical techniques and that reviews their application to archaeology. It explains key terminology, outlines the procedures to be followed in order to produce good data, and describes the function of the basic instrumentation required to carry out those procedures. The manual contains chapters on the basic chemistry and physics necessary to understand the techniques used in analytical chemistry, with more detailed chapters on atomic absorption, inductively coupled plasma emission spectroscopy, neutron activation analysis, X-ray fluorescence, electron microscopy, infrared and Raman spectroscopy, and mass spectrometry. Each chapter describes the operation of the instruments, some hints on the practicalities, and a review of the application of the technique to archaeology, including some case studies. With guides to further reading on the topic, it is an essential tool for practitioners, researchers, and advanced students alike. 

This book was conceived also to answer the readership needs in the area of Analytical Chemistry, whether it be for study within this discipline or as a tool used in other experimental sciences and diverse areas. The background knowledge required to profit from this book is essentially that possessed by students in their first years of university. Thus, the authors have limited themselves to fundamental principles and have considered that students already have basic training in mathematics and in the approach to studying physical phenomena. Throughout this book, in-depth studies of phenomena have been avoided in order not to put off the majority of readers at whom this book is targeted. Those interested will, if necessary, be able to consult specialised works without any major difficulties, after having acquired from this book a relatively complete overview of the most currently used methods. 

Abstract The fact that various definitions and terminology applied to measurements in analytical chemistry are not always consistent and straightforward, by not only answering the question what , but also how , leads to their various interpretations. This results in non-uniform implementation of very basic and essential metrological principles in chemistry. Such a diverse situation is not conducive to the endorsement of harmonised measurements all across the world, to serve as a tool for improving the quality of life in its broadest sense for all its citizens. The discussion in this paper is focused on problems associated with terminology and definitions of reference material and validation .
