Excerpt from A Manual for Assayers and Chemists An impression prevails that the results reported by technical analysts are less accurate and reliable than those reported by so-called scientific analysts. This is supposed to be due to the superiority of scientific over technical methods, as well as to a lack of skill in technical analysts. The work of all technical analysts is subject to frequent and careful checking by the slowly working scientific chemists, as well as by technical chemists of the highest skill; consequently all technical errors are certain of discovery and the imperfections in the methods are quickly brought to light. It may be that the general impression is correct, but until the work of scientific chemists is subjected to the same rigid checking the data upon which to base an accurate opinion will always be lacking. The results of the scientists ought to be more accurate than those of the technical analysts, because they are not hurried and can take the time to test, step by step, the perfection of each separation; but after everything has been said, the question of method is of less importance than the care and understanding which each individual analyst may put into his work. Technical methods must be quick, and there is a constantly increasing pressure that they shall give results as near to absolute accuracy as is possible to attain. Whatever improve ments are desirable in these methods must come from the work of technical analysts, working daily, in absolute touch with the varying conditions in widely separated localities.

For students, DIY hobbyists, and science buffs, who can no longer get real chemistry sets, this one-of-a-kind guide explains how to set up and use a home chemistry lab, with step-by-step instructions for conducting experiments in basic chemistry -- not just to make pretty colors and stinky smells, but to learn how to do real lab work: Purify alcohol by distillation Produce hydrogen and oxygen gas by electrolysis Smelt metallic copper from copper ore you make yourself Analyze the makeup of seawater, bone, and other common substances Synthesize oil of wintergreen from aspirin and rayon fiber from paper Perform forensics tests for fingerprints, blood, drugs, and poisons and much more From the 1930s through the 1970s, chemistry sets were among the most popular Christmas gifts, selling in the millions. But two decades ago, real chemistry sets began to disappear as manufacturers and retailers became concerned about liability. ,em>The Illustrated Guide to Home Chemistry Experiments steps up to the plate with lessons on how to equip your home chemistry lab, master laboratory skills, and work safely in your lab. The bulk of this book consists of 17 hands-on chapters that include multiple laboratory sessions on the following topics: Separating Mixtures Solubility and Solutions Colligative Properties of Solutions Introduction to Chemical Reactions & Stoichiometry Reduction-Oxidation (Redox) Reactions Acid-Base Chemistry Chemical Kinetics Chemical Equilibrium and Le Chatelier's Principle Gas Chemistry Thermochemistry and Calorimetry Electrochemistry Photochemistry Colloids and Suspensions Qualitative Analysis Quantitative Analysis Synthesis of Useful Compounds Forensic Chemistry With plenty of full-color illustrations and photos, Illustrated Guide to Home Chemistry Experiments offers introductory level sessions suitable for a middle school or first-year high school chemistry laboratory course, and more advanced sessions suitable for students who intend to take the College Board Advanced Placement (AP) Chemistry exam. A student who completes all of the laboratories in this book will have done the equivalent of two full years of high school chemistry lab work or a first-year college general chemistry laboratory course. This hands-on introduction to real chemistry -- using real equipment, real chemicals, and real quantitative experiments -- is ideal for the many thousands of young people and adults who want to experience the magic of chemistry.

Based on the Laboratory Analyst Training and Certification Program ... chemists from a range of pharmaceutical companies and a few academic laboratories explain how to comply with the US Food and Drug Administration's Good Manufacturing Practice rules as analytical technologies are changing rapidly .... Among the topics are the drug development process, uniform and consistent interpretation of compliance issues, the role of statistics and basic topics in analytical chemistry, and detectors and quantitative analysis. The emphasis is on high-performance liquid chromatographic methods.

Though many practical books are available in the market but this Laboratory Manual of Microbiology, Biochemistry and Molecular Biology is an unique combination of protocols that covers maximum (about 80%) of the practicals of various Indian universities for UG and PG courses in Bioscience, Biotechnology, Microbiology, Biochemistry and Biochemical Engineering.

The present book ‘Comprehensive Laboratory Manual of Life Science’, deals with practical trends in modern biological sciences. It furnishes protocols on recent advances in biotechnological methods and aims to cover three most important aspects of this interdisciplinary stream; such as Microbiology, Biochemistry and Molecular biology. The book contains four sections: 1. Introduction: emphasizes on good laboratory practices and etiquettes for beginners; the do’s and don’ts of working in a laboratory, concepts and terminology, etc. 2. Instruments: Principle and Precautions: explores commonly used equipments employed in different experiments. 3. Experiments: is further divided into three parts: Microbiology with more than 70 experiments, Biochemistry with 62 and Molecular Biology having around 32 detailed protocols, accorded to make the readers proficient in the paramount disciplines of Bio Sciences and Biotechnology. 4. Appendix: at the end, a rather comprehensive section that concludes the book. This book is designed to meet the practical requirements of undergraduate and post graduate students of Life Science, Biotechnology, Microbiology, Biochemistry and Biochemical Engineering by providing worked out solution to the most commonly practiced experiments prescribed by majority of Indian Universities. The latest technological developments in the book will be appealing to the researchers and scientists
