## Principles of instrumental analysisPRINCIPLES OF INSTRUMENTAL ANALYSIS places an emphasis on the theoretical basis of each type of instrument, its optimal area of application, its sensitivity, its precision, and its limitations.You'll also learn about elementary analog and digital electronics, computers, and treatment of analytical datA. Visit the book companion website for tutorials on instrumental methods, Excel files of data analysis and simulations of analytical techniques to help you visualize important concepts in this course, and selected papers from the chemical literature to stimulate interest and provide background information for study. |
