Instrumental Analysis

Excerpt

This book has been written as a text for a course in instrumental analysis given to senior and graduate chemistry students at Rensselaer Polytechnic Institute. The course is designed to familiarize the students with the operation of the major analytical instruments and the possible applications of these instruments to their research problems and their future work in the field of chemistry.

A great deal of instrumentation is used in the modern courses in physics and physical chemistry, but this equipment is usually constructed or assembled in the laboratory and the emphasis is on the system being measured rather than on the instruments themselves. The present course recognizes that, in general, the analytical chemist uses commercial instruments for the determination of various elements or compounds. Therefore, the emphasis is less on the particular system being measured than on the utility of the several types of instruments and on a broad picture of the field of commercial instruments. The student who has this training will be in a position to select instruments for a particular problem with some idea of the advantages and disadvantages of the types that are available.

The selection of the equipment to be included in the text has been decided by the actual units available at Rensselaer. The simple instruments whose analytical uses are considered in the usual undergraduate courses in physical and organic chemistry have not been discussed again. An attempt has been made to describe the principles that are basic to the various types of instrumental analysis and to describe some of the commercial models of instruments that are presently available. Although the rapid changes and improvements being made in commercial instruments may make some of the descriptions obsolete, the principles learned should carry over to new equipment as it appears on the market.
