Analytical Chemistry, Volume 4Wiley, 2003 - 828 pagine This text is designed for the undergraduate one-term Quantitative Analysis course (sometimes called Analytical Chemistry) for students majoring in Chemistry and related fields. It deals with principles and techniques of quantitative analysis. Examples of analytical techniques are drawn from such areas as life sciences, clinical chemistry, air and water pollution, and industrial analyses.The Sixth Edition is extensively revised and updated with a more modern flavor and a new, two-color design. |
