REPORT FOR ANALYTICAL CHEMISTS
after graduation will be necessary for all to keep abreast of new developments in chemistry; no scientific worker can ever quit studying.
Educational institutions cannot be expected to train students in specific areas of chemistry or in specific techniques to directly fulfill industry's needs. Industry must assume responsibility for specific training and practice in its specific areas of work. For work in industrial analytical chemistry, however, the graduate should have, in addition to a good chemical education, a basic understanding of the principles and the potential of all the modern analytical techniques on which he can draw as needed. Coverage of these many techniques should be aided by combining different topics, often taught separately, in the manner outlined by Reilley (3) viz., the interaction of electromagnetic radiation with matter: principles of rotational, vibrational, and electronic transitions; their corresponding absorption and emission spectra; and the relationship between spectra and chemical structure. Similar coverage can be given also to the electrochemical area, and it should be possible to group the methods for chemical separations—a most important part of chemical analysis-—for a reasonable understanding of them. Within these two sentences alone might be named nearly all the principal techniques of analytical chemistry, or at least most of the important modern ones, which too often are thought of and taught as separate entities. Some practice with "live problems" too, as mentioned by Rogers (4) is desirable. Given the basic principles, the theory, and the advanced concepts of the latest thinking on structure of matter in his early college work, a student interested in analytical chemistry should be able to relate and to think in terms of the techniques of analytical chemistry.
Industry needs and will continue to need competent interested people educated in analytical chemistry—· B.S., M.S., and Ph.D.—who can be trained to accept the responsibilities at all levels in this vital area of its work. I t is recognized that many analyses are and should be carried out directly by synthesis
chemists and others and that they, too, need to be educated in the principles of analytical chemistry. Generally, however, they cannot cf-ficently pursue their main objectives and at the same time be truly proficient in analytical chemistry. Their employment of a single analytical approach or selection of an analytical method or instrument just because it is known or conveniently available, "one instrument research," needs to be guarded against. Competitive industry must have accurate and as complete information about the composition of its products and materials as it can practically obtain.
The opportunities for growth and advancement of an analytical chemist in industry are limited only by his ability and the amount of initiative, effort, and judgment he exercises. Rewarding careers are to be had in industrial analytical chemistry ; training in this field provides a valuable basis for work in other fields as well.
Kolthoff (1) writes "analytical chemists are part of the team that includes all other chemists and engineers who are being consulted in the search for solutions to problems which arise in producing, processing, and characterizing an industrial product." As "partners in this team," industrial and academic analytical chemists must keep alert to responsibilities of this discipline and cooperate in fulfilling them.
For the education of analytical chemists, the plea is to continue searching for the best ways to bring together and coordinate all the principles and tools of analytical chemistry so as to attract, interest, and develop an analytical viewpoint in the minds of a proportionate number of the able chemistry students for analytical work—both for industrial employment and for continued teaching of the subj ect.
