Through an analytical approach, Essential Methods of Instrumental Analysis provides an expansive overview of common instruments and methods and their applications for undergraduate students, integrating experimental protocols with real result examples to deliver a well-rounded understanding of the inner workings of the instruments and enabling students to evaluate the success of their experiments and create scientific figures.
In addition to detailed coverage of specific instruments, the book discusses analytical laboratory practices, instrument maintenance, statistics, and real-world lab experiments with previous student results. Each analytical method section includes extensive sample preparation information, rather than a simple stand-alone chapter offering generic discussions not connected to specific methods.
This book conveniently organizes content by analyte class (inorganic and organic) in a way that is intuitive to a student and aligned with relevant courses. Ancillaries including .mp4 videos, instructor PowerPoint slides, and animations are included on a companion website.
Written by an experienced professor and tested and refined over years in his courses since 2008, Essential Methods of Instrumental Analysis includes information on sample topics such as: - Proper laboratory protocols for analytical instrumentation, covering chemical reagents, glassware, calibration techniques, and figures of merit- Optical physics, covering the interaction of electromagnetic radiation with instrument components and sample molecules, relaxation processes, reflection, diffraction, dispersion, and refraction- Flame atomic absorption and flame emission spectrometry, covering optical radiation sources, mirrors, choppers, burner heads, and doppler broadening- Gas and liquid chromatography, covering gaseous, liquid, soil-sediment, and biological samples, analyte recovery, chromatography theory, injectors, columns and ovens, common detectors, and mass spectrometers
Focusing on contrasts and comparisons across multiple types of instruments in a way distinct from similar texts, Essential Methods of Instrumental Analysis is an essential textbook for students in advanced undergraduate courses in related programs of study.
