Analytical chemistry is the science of obtaining, processing, and communicating information about the composition and structure of matter. In other words, it is the art and science of determining what matter is and how much of it exists. Analytical chemists use their knowledge of chemistry, instrumentation, computers, and statistics to solve problems in almost all areas of chemistry and for all kinds of industries. For example, their measurements are used to assure the safety and quality of food, pharmaceuticals, and water; to assure compliance with environmental and other regulations; to support the legal process; to help physicians diagnose diseases; and to provide measurements and documentation essential to trade and commerce. Analytical chemists often work in service-related jobs and are employed in industry, academia, and government. They conduct basic laboratory research; perform process and product development; design instruments used in analytical analysis; teach; and work in marketing and law. Analytical chemistry can be a challenging profession that makes significant contributions to many fields of science (https://www.acs.org) Read more »

Recomended Ebook For TOEFL Preparation: 400 Must Have Words for the TOEFL
Test of English as a Foreign Language (TOEFL) is a standardized test to measure the English language ability of non-native speakers wishing to enroll in English-speaking universities. The test is accepted by many English-speaking academic and professional institutions. TOEFL is one of the two major English-language tests in the world, the other being the IELTS. TOEFL is a trademark of the Educational Testing Service (ETS), a private non-profit organization, which designs and administers the tests. ETS issues official score reports, sent independently to institutions, for two years following the test (wikipedia).
For students whose first language is not English and who wish to study at a university with an English-based curriculum, no admittance test is more important than the Test of English as a Foreign Language (TOEFL). 400 Must-Have Words for the TOEFL helps you score well by arming you with the most important English vocabulary words commonly found on this crucial exam. This timely guide also encompasses the recent changes made to the test, including the emphasis on conversation and spontaneous communication to mirror the interactive nature of the classroom.

Chemistry Ebook: Mass Spectrometry Instrumentation, Interpretation, and Applications
The first part of this book is dedicated to a discussion of mass spectrometry (MS) instrumentation. We start with a list of basic definitions and explanations (Chapter 1). Chapter 2 is devoted to the mass spectrometer and its building blocks. In this chapter we describe in relative detail the most common ion sources, mass analyzers, and detectors. Some of the techniques are not extensively used today, but they are often cited in the MS literature, and are important contributions to the history of MS instrumentation. In Chapter 3 we describe both different fragmentation methods and several typical tandem MS analyzer configurations. Chapter 4 is somewhat of an outsider. Separation methods is certainly too vast a topic to do full justice in less than twenty pages. However, some separation methods are used in such close alliance with MS that the two techniques are always referred to as one combined analytical tool, for example, GC-MS and LC-MS. In effect, it is almost impossible to study the MS literature without coming across at least one separation method. Our main goal with Chapter 4 is, therefore, to facilitate an introduction to the MS literature for the reader by providing a short summary of the basic principles of some of the most common separation methods that have been used in conjunction with mass spectrometry.
