Laboratory analytical teaching

Carl Remigius Fresenius (Frankfurt, 28 December 1818-Wiesbaden, ii June 1897), assistant to Liebig at Giessen, established (1848) an analytical teaching laboratory in Wiesbaden and was professor in the Agricultural Institute there (1845-76). Fresenius wrote books on qualitative and quantitative analysis which went through numerous editions and translations. ... 

The textbook on Pharmaceutical Drug Analysis would enormously serve the undergraduates, postgraduates, researchers, analytical chemists working in the Quality Assurance Laboratories, new drug development, production and control, teaching, or regulatory authorities. 

There are a number of critical elements in an efficient university clinical pharmacology department. They include teaching, analytical and experimental laboratory work, clinical service, drug information and critical appraisal, advisory support for the professions, drug safety research and evaluation, and pharmacovigilance. 

Today a variety of complex methods are used in laboratories. This book describes these methods in a simple, systematic, yet precise, way. Well-balanced introductions are provided for all chromatographic separation techniques and for methods of structure identification. Its many explanations make this book an indispensable teaching aid for aspiring analytical chemists. 

Classical laboratory, manual methods conducted on a macro-scale where sample quantities arc in the range of grams and several milliliters. These are the techniques that developed from the earliest investigations of chemistry and which remain effective for teaching the fundamentals of analysis. However, these methods continue to be widely used in industry and research, particularly where there is alarge variety of analytical work to be performed. The equipment, essentially composed of analytical balances and laboratory glassware, tends to be of a universal nature and particularly where budgets for apparatus are limited, the relative modest cost of such equipment is attractive. 

Background and principles UV spectroscopic analysis was one of the first applications of spectroscopy in an analytical context. While a powerful technique of yesteryear, this method is now rather restricted in its use in a modem bioanalytical laboratory. However, UV/visible spectroscopy is still used in specific biochemical analyses, such as dyestuffs in forensic applications. Despite these limitations, a bench spectrophotometer that measures UV/visible absorbance is commonly found in both teaching and research laboratories. In order to better understand the underlying principles it is necessary to consider the excitation of electrons, electronic transition and how this is related to energy and absorbance. 

Butyl ether is used mainly as a solvent for organic materials such as resins, oils, hydrocarbons, esters, gums, and alkaloids. It is also used as an extracting agent in metal separation and as a reacting medium in organic synthesis processes. It is a solvent commonly found in teaching, research, and analytical laboratories. 

Our major objective of this text is to provide a thorough background in those chemical principles that are particularly important to analytical chemistry. Second, we want students to develop an appreciation for the difficult task of judging the accuracy and precision of experimental data and to show how these judgments can be sharpened by the application of statistical methods. Our third aim is to introduce a wide range of techniques that are useful in modern analytical chemistry. Additionally, our hope is that with the help of this book, students will develop the skills necessary to solve analytical problems in a quantitative manner, particularly with the aid of the spreadsheet tools that are so commonly available. Finally, we aim to teach those laboratory skills that will give students confidence in their ability to obtain high-quality analytical data. 

In order to test class identification based on multi-color native fluorescence we have measured LIF spectra for representative bio-agent simulants in solution for various classes of bio-molecules (i.e., toxins, viruses and bacteria) with a conventional laboratory set-up. For a proof-of-concept, the library of spectra was subjected to a mathematical procedure to extract and evaluate distinguishing features of the analytes. In a second step, the extracted distinguishing features were used to teach a multidimensional classifying... 

Eric Malina has a BSEd in secondary chemistry teaching from Southwest Missouri State University, taught secondary science and mathematics and has a PhD in Science Education from Purdue University. He also spent two years in graduate study of analytical chemistry at University of Missouri-Columbia. His MS in chemistry education from Purdue University focused on the impact of scientific instmment on chemistry student attitudes towards science. His PhD research focused on the impact of scientific instmmentation on college student learning in the laboratory. He is currently an Assistant Professor at Southern Illinois University, Edwardsville. 

Dr John Baker left Cambridge to become a Fulbright Scholar in the USA, and subsequently worked at Bristol University before joining the Schuster Physics Laboratory at the University of Manchester. He is currently Visiting Reader in the Department of Instrumentation and Analytical Science at UMIST. Both authors are widely published and have extensive teaching and research experience.
