REPORT FOR ANALYTICAL CHEMISTS techniques as they have come along. We have indeed anticipated the ex cellent advice given by L. T. H a l l e t t in these columns a few years ago under t h e heading "Selecting t h e Right Analytical M e t h o d " ( 7 ) : " T h e answer," he said, "which is gradually being recognised, is to or ganise the analytical d e p a r t m e n t so t h a t it h a s both t h e chemical a n d instrumental to offer as service and so obviates t h e wasteful process of customers shopping around to get their analytical problems solved." Every problem submitted can be considered against this background and the n a t u r e of t h e examination planned in such a way as to give t h e information required, a n d not a l ways t h a t initially requested for, as R. P . C h a p m a n p u t it, " a t a n y point along the line . . . . questions m a y be raised as to the propriety of t h e request, the possibility t h a t d a t a not specified might be more useful, or the addition of background in formation which might be more helpful." By co-ordination a n d integration of these m a n y techniques of exami nation, in particular in the case of inorganic materials, it is possible to give the quantitative composition in terms of major, minor, and trace elements ; t h e state of combination ; the concentration a n d distribution of impurity phases: evidence of inhomogeneity or nonstoichiometry ; the ultimate crystal size; t h e exist ence of polymorphic forms; t h e n a ture of the surface layers where these differ from the body structure of t h e material. I t is perhaps not so i m p o r t a n t to stress, with Liebhafsky, t h a t t h e chemistry is going o u t of analytical chemistry b u t rather to emphasize t h a t physics is coming i n ; our a n a lytical division has for long in cluded a substantial proportion of physicists. Indeed, to match u p to the requirements of a modern ana lytical unit the analyst m a y have to be something of a chemist, physicist, metallurgist, mineralogist, bacteri ologist, and electronics engineer, all in one. I n some circumstances t h e place of the analyst is t a k e n by a team of specialists, some of whom would formerly have h a d no place in the traditional analytical labora tory-,
While t h e a n a l y s t h a s therefore an i m p o r t a n t a n d essential p a r t to play in industrial research, his r e sponsibilities are heavy, for besides his specialist knowledge a n d skills he must also become so knowledge able as to be able to discuss intelli gently the problems of t h e other r e search groups t o whom he has a service to offer. H e must also be prepared to explain a n d to interpret the significance of his own contribu tion.

TYGON® Clear • Flexible • Plastic
TUBING
Summary To sum u p , i t is not only t h e techniques of analysis t h a t have been affected by t h e revolution of the last 15 y e a r s ; it is more particu larly t h e objects a n d t h e purpose of analysis a n d above all t h e concep tion of w h a t analysis comprises. Against this background it is per haps not very profitable to discuss the s t a t u s of t h e a n a l y s t on either side of t h e Atlantic until there is a clearer recognition as to w h a t con stitutes an analyst a n d what is now included in t h e obsolescent term "analytical chemistry." Above all, it is urgently necessary t h a t this re-appraisal should be made and understood in academic circles everywhere, so t h a t it m a y be real ised t h a t it is t h e best and not the second-rate m a n t h a t is needed for analytical work and t h a t a worth while, if demanding, career is open to him.

because set-ups are so fast and easy with Tygon Tubing's rub ber-like flexibility (yet Tygon is clear as glass, permitting visual examination of flow at any point);
... and SAVES because one tubing can be used to handle all chemicals found in the laboratory, thanks to Tygon's extremely broad range of chemical resistance (it's quick and easy to flushclean, too);
...
and
SAVES
because non-aging, tough Ty gon Tubing retains its unique characteristics throughout an amazingly long service life.
