With the birth of the electronic hand calculator and the death of the slide rule, the teaching of general chemistry entered a new era. Unfortunately, the alculator did not bring automatic understanding of chemistry; analyzing and solving problems is just as difficult as ever. The need for detailed explanations, drill, and review problems is still with us. This book, "Solving General Chemistry Problems", by R.N. Smith, is a replication of a book originally published before 1980. It has been restored by human beings, page by page, so that you may enjoy it in a form as close to the original as possible. This book was created using print-on-demand technology. Thank you for supporting classic literature.

Lets you target the specific information you need quickly and easily -so you can stay in the lab and out of the library. This invaluable database -available in print and electronic form -gives you fast, hands-on access to the most significant literature available on HPLC for the analysis of over 150 of the most frequently prescribed pharmaceutical compounds. Combining full descriptions of procedures with specially annotated references, HPLC Methods for Pharmaceutical Analysis helps you to identify the techniques that are relevant to your individual project needs -eliminating hours of tedious, time-consuming library research. Analytical chemists and researchers will find a battery of useful features that make this practical new resource a welcome addition to their reference library: Techniques for each compound are described in detail -enabling replication of a procedure without reference to the original publication Detailed procedures for each drug are listed together -making it easy to combine features of different methods into a customized approach Drug assay methods are provided for drugs in biological fluids such as blood or urine, as well as for bulk and formulated drugs Other key information includes chemical structures, molecular weights and formulas, CAS Registry Numbers, and cross-references to The Merck Index and Chemistry of Drug Synthesis The electronic version, available on CD-ROM, allows you to search the entire database by compound, matrix, HPLC variables, and author.
