Chemistry can be a daunting subject for the uninitiated, and all too often, introductory textbooks do little to make students feel at ease with the complex subject matter. Basic Chemistry Concepts and Exercises brings the wisdom of John Kenkel‘s more than 35 years of teaching experience to communicate the fundamentals of chemistry in a practical, down-to-earth manner.Using conversational language and logically assembled graphics, the book concisely introduces each topic without overwhelming students with unnecessary detail. Example problems and end-of-chapter questions emphasize repetition of concepts, preparing students to become adept at the basics before they progress to an advanced general chemistry course. Enhanced with visualization techniques such as the first chapter‘s mythical microscope, the book clarifies challenging, abstract ideas and stimulates curiosity into what can otherwise be an overwhelming topic. Topics discussed in this reader-friendly text include:Properties and structure of matter Atoms, molecules, and compounds The Periodic Table Atomic weight, formula weights, and moles Gases and solutions Chemical equilibrium Acids, bases, and pH Organic chemicalsThe appendix contains answers to the homework exercises so students can check their work and receive instant feedback as to whether they have adequately grasped the concepts before moving on to the next section. Designed to help students embrace chemistry not with trepidation, but with confidence, this solid preparatory text forms a firm foundation for more advanced chemistry training.

Today's industrial laboratory analyst encounters issues such as quality control, quality assurance ISO 9000, standard operating procedures, calibration, standard reference materials, statistical control, control charts, proficiency testing, validation, system suitability, chain of custody, good laboratory practices, protocol, and audits. In a well-written and readable style, A Primer on Quality in the Analytical Laboratory provides an introduction to quality, standards, and regulations in the analytical laboratory and serves as a valuable resource to a myriad of laboratory practices.Features

Written as a training manual for chemistry-based laboratory technicians, this thoroughly updated fourth edition of the bestselling Analytical Chemistry for Technicians emphasizes the applied aspects rather than the theoretical ones. The book begins with classical quantitative analysis and follows with a practical approach to the complex world of sophisticated electronic instrumentation commonly used in real-world laboratories. Providing a foundation for the two key qualities—the analytical mindset and a basic understanding of the analytical instrumentation—this book helps prepare individuals for success on the job.Chapters cover sample preparation; gravimetric analysis; titrimetric analysis; instrumental analysis; spectrochemical methods, such as atomic spectroscopy and UV-Vis and IR molecular spectrometry; chromatographic techniques, including gas chromatography and high-performance liquid chromatography; electroanalytical methods; and more. Incorporating an additional ten years of teaching experience since the publication of the third edition, the author has made significant updates and enhancements to the fourth edition. More than 150 new photographs and either new or reworked drawings spanning every chapter to assist the visual learnerA new chapter on mass spectrometry, covering GC-MS, LC-MS, LC-MS-MS, and ICP-MSThirteen new laboratory experimentsAn introductory section before chapter 1 to give students a preview of general laboratory considerations, safety, laboratory notebooks, and instrumental analysisAdditional end-of-chapter problems, expanded "report"-type questions, and inclusion of relevant section headings in the Questions and Problems sectionsApplication Notes in each chapterAn appendix providing a glossary of quality assurance and good laboratory practice (GLP) terms

Have you ever had a discussion with an industrial chemist about the job? Have you ever shadowed a chemist or chemical technician in an industrial or government laboratory for a day? If you have done these things, you were likely surprised at how foreign the language seemed or startled at how unfamiliar the surroundings were. Was there any talk of the quantum mechanical model of the atom? No. Was there any activity relating to Molecular Orbital Theory of bonding? No. Was the lab a large room with six 12-foot lab benches capable of accommodating up to two dozen chemists? No, not usually.Unless you took an "industry based" chemistry course, you probably came away from this experience with the thought "Why don't textbooks and lab manuals do a better job of communicating what real-world chemists do?" Chemistry: An Industry-Based Laboratory Manual does just that. It covers laboratory safety, record-keeping, control charts, certified reference materials, and much more."Who uses this stuff anyway?" you may ask. Chemistry: An Industry-Based Laboratory Manual supplies the answer. It features applications of basic chemistry concepts to the real-world work of chemistry professionals. It brings real-world examples to laboratory experiences and covers voluntary industry standards for laboratory workers in the chemical process industries. It places a strong emphasis on the real work of chemistry professionals.
