Excerpt from A Laboratory Guide for Beginners in Chemical Analysis The formulae made use of in this work to describe compounds, are molecular formulae; that is, they express the weight which, in the gaseous state, they have, referred to H, volume for volume, this is not the place to describe the methods by which the molecular volumes of volatile and nonvolatile bodies have been determined. The molecule we believe to be composed of atoms having the smallest proportion, by weight, of the element which can enter into combination. The atoms unite with one another to form molecules, in which their affinities are mutually satisfied: the measure of affinity is different for different atoms: the elements differ in quantivalency or atomicity. The measure of the atom of hydrogen, H, is selected as a basis; it is univalent, and is, as it were, a point of departure for other atoms. The metalloids are called univalent, bivalent, trivalent, etc., according as an atom is able to unite with, or replace, one, two or three atoms of hydrogen. The quantivalency of the metals depends upon the number of hydrogen atoms which the metal-atom can replace. Probably every atom has a fixed capacity for saturation a fixed chemical value.

Often considered as a simple task, chemical analysis actually requires a variety of quite complex skills. As a practitioner in an interdisciplinary science, the analytical scientist is relied upon to have the knowledge and skill to help solve problems or to provide relevant information. They will need to think laterally, examine the process from sampling to final result carefully, in addition to selecting the appropriate technique in order to satisfy the objective and obtain a reliable result. The aim of this book is to provide basic training in the whole analytical process for students, demonstrating why analysis is necessary and how to take samples, before they attempt to carry out any analysis in the laboratory. Initially, planning of work, and collection and preparation of the sample are discussed in detail. This is followed by a look at issues of quality control and accreditation and the basic equipment (eg. balances, glassware) and techniques that are required. Throughout, safety issues are addressed, and examples and practical exercises are given. Chemical Analysis in the Laboratory: A Basic Guide will prove invaluable for students of chemistry, plant science, food science, biology, agriculture and soil science, providing them with a guide to the skills that will be required in the Analytical Laboratory. Teachers and lecturers will also find the material of assistance in developing the analytical thinking and skills of their students. New employees in analytical laboratories will welcome it as an indispensable guide.

Chemical data analysis, with aspects of metrology in chemistry and chemometrics, is an evolving discipline where new and better ways of doing things are constantly being developed. This book makes data analysis simple by demystifying the language and whenever possible giving unambiguous ways of doing things. Based on author D. Brynn Hibberts lectures on data analysis to undergraduates and graduate students, Data Analysis for Chemistry covers topics including measurements, means and confidence intervals, hypothesis testing, analysis of variance, and calibration models. The end result is a compromise between recipes of how to perform different aspects of data analysis, and basic information on the background principles behind the recipes to be performed. An entry level book targeted at learning and teaching undergraduate data analysis, Data Analysis for Chemistry makes it easy for readers to find the information they are seeking to perform the data analysis they think they need.
