The first edition of "Chromatography: Concepts and Contrasts," published in 1988, was one of the first books to discuss all the different types of chromatography under one cover. The second edition continues with these principles but has been updated to include new chapters on sampling and sample preparation, capillary electrophoresis and capillary electrochromatography (CEC), chromatography with mass spec detection, and industrial and governmental practices in regulated industries.

• Covers extraction, solid phase extraction (SPE), and solid phase microextraction (SPME), and introduces mass spectrometry
• Updated with the latest techniques in chromatography
• Discusses both liquid chromatography (LC)and gas chromatography(GC)

How to hone your analytical skills and obtain high-quality data in the era of GMP requirements

With increased regulatory pressures on the pharmaceutical industry, there is a growing need for capable analysts who can ensure appropriate scientific practices in laboratories and manufacturing sites worldwide. Based on Johnson & Johnson's acclaimed in-house training program, this practical guide provides guidance for laboratory analysts who must juggle the Food and Drug Administration's good manufacturing practices (GMP) rules with rapidly changing analytical technologies. Highly qualified industry experts walk readers step-by-step through the concepts, techniques, and tools necessary to perform analyses in an FDA-regulated environment, including clear instructions on all major analytical chemical methods-from spectroscopy to chromatography to dissolution. An ideal manual for formal training as well as an excellent self-study guide, Analytical Chemistry in a GMP Environment features:

• The drug development process in the pharmaceutical industry
• Uniform and consistent interpretation of GMP compliance issues
• A review of the role of statistics and basic topics in analytical chemistry
• An emphasis on high-performance liquid chromatographic (HPLC) methods
• Chapters on detectors and quantitative analysis as well as data systems
• Methods for ensuring that instruments meet standard operating procedures (SOP) requirements
• Extensive appendixes for unifying terms, symbols, and procedural information

"Man's natural instinct, in fact, is never toward what is sound and true. It is toward what is specious and false . . . The ideas that conquer the race most rapidly and arouse the wildest enthusiasm and are held most tenaciously are precisely the ideas that are most insane. This has been true since the first 'advanced' gorilla put on underwear, cultivated a frown and began his first lecture tour, . . . " H. L. Mencken, from Meditation On Meditation in the Smart Set, June, 1920 pp 45-46 In our opinion there is no field of clinical medicine in such a state of dynamic disequilibrium as clin ical thyroidology. Thyroid diseases are very common. The moderately complex but easily understandable physiological interrelationships between the thyroid, pituitary and hypothalamus have provided stimuli for the application of mod ern technology in the development of an array of diagnostic procedures. Although therapeutic methods have been more stable, and recent advances more limited, their application by phy- Joel I. Hambufl er. M. D. sicians representing different disciplines has pro vided an ample basis for the expression of differ ing viewpoints. Unfortunately there are few opportunities for in-depth exploration of different attitudes and experience relevant to issues of current interest. The review process employed by medical journals often seems to stifle the expression of controver sial viewpoints."

The face of infectious diseases has changed since the second edition of A Guide to Specimen Management in Clinical Microbiology was published in 1999. Despite improved surveillance and vaccinations, tens of millions of people visit physicians annually for a possible microbial or parasitic infection. Identifying the infectious agent in a patient remains a top priority, and proper identification begins with careful collection, appropriate packaging and transport, and responsible reporting of patient specimens. For these reasons, A Guide to Specimen Management in Clinical Microbiology is as essential as ever. The book is divided into four sections and features tips and words of wisdom that come directly from experts in the field. Communicating laboratory needs explains to all members of the healthcare team what role the clinical microbiology laboratory plays in patient care. It also emphasizes that microbiology specimens contain living organisms that require proper handling to remain viable. Specimen management policies and rationale provides a framework for creating a specimen management policy and a specimen collection and handling manual that, together, support good medicine and good laboratory practice. Specimen collection and processing contains detailed protocols for selecting, collecting, storing, and transporting adult and pediatric specimens to the clinical microbiology laboratory. This section can serve as a model for preparation of the specimen management manual. Specimen management summary tables are handy reference guides that provide answers to most questions regarding the laboratory needs for a wide variety of bacterial, viral, fungal, and parasitic organisms found in patient specimens. Because patient care is a team effort, all members of the health care teamaEURO"physicians, nurses, nurse practitioners, physician assistants, specimen collectors, and laboratoriansaEURO"will benefit greatly from reading this book.

In 1901 the National Bureau of Standards (NBS) was founded to provide standard weights and measures and to be the national physical laboratory for the United States of America. The NBS conducted a lot of research in the fields of science and technology which were reported as "Scientific Papers." In 1988 the NBS became what we know now; the National Institute of Standards and Technology (NIST). This is one of those documents written by employees of the NBS.
