Principles of Instrumental AnalysisSaunders College Pub., 1998 - 849 pagine This text is written for a course that deals with the principles and applications of modern analytical instruments. Emphasis is placed upon the theoretical basis of each type of instrument, its optimal area of application, its sensitivity, its precision, and its limitations. The text also introduces students to elementary integrated circuitry, microprocessors and computers, and treatment of analytical data. |
