educate students to be experts in certain areas. Industries will be able to obtain spectroscopists from some schools, radiochemists from other schools, and so forth. The analytical chemist must have sufficent education in all fields of chemistry (organic, inorganic, bio-, physical and engineering) in order to apply modern chemistry and instrumentation to problems so that his measurements are informative. In my opinion the undergraduate chemist should have a good course in the freshman or sophomore year emphasizing quantitative measurements and covering basic principles of solution chemistry, separations, electrochemistry, and spectroscopy. In the senior year there should be a specialized course related to problem solving involving spectroscopic-structure techniques and separation-identification-measuring methods which takes advantage of the particular professor's field of research. This course should be divided when possible between the various professors in analytical chemistry so that experience could be obtained from each. I feel this would be stimulating to the student and could lead to a career in analytical chemistry directly or through the graduate school. (J!) Reilley, C. N., A N A L . C H E M . 38, 35 A

Faster, more efficient Zone Refining with

New MRC Multizone I Organic and Chemical Zone Refiner

of M . T . KELLEY

In reading the report on "New Horizons in Education" by Charles N. Reilley and others in the February issue of ANALYTICAL CHEMISTRY, I find that I am in agreement with many of the ideas presented. As the Director of the Analytical Chemistry Division of a large research organization, I believe it would be deplorable if the trend toward minimizing analytical chemistry as a part of the chemistry curriculum were to be continued to the point that analytical chemistry would disappear as one of the major subdivisions of chemistry. I feel that analytical chemistry should continue to hold an important place not only in the undergraduate curriculum but also in the graduate curriculum. While it is true that many of the principles underlying analytical chemistry and the techniques used by analyt-

The MRC Multizone I Organic and Chemical Zone Refiner performs faster and more efficiently than conventional vertical zone refiners! It cuts the critical personnel time usually needed for zone refining . . . improves the end product! The credit for its superior performance goes to new, patented heating and cooling techniques that obtain flat liquid-solid interfaces in combination with short zone lengths and interzone spacing. Multizone I operates with many materials . . . can be used in applications that require zone refining, zone leveling, normal freezing and single crystal growth.
