This third edition of Analytical Chemistry for Technicians is the culmination and final product of a series of four projects funded by the National Science Foundation’s Advanced Technological Education Program and two supporting grants from the DuPont Company. The grant funds have enabled me to utilize an almost limitless reservoir of human and other resources in the development and completion of this manuscript and to vastly improve and update the previous edition. A visible example is the CD that accompanies this book. This CD, which was not part of the previous editions, provides, with a touch of humor, a series of real-world scenarios for students.
