Chromosorb 105 is a polyaromatic porous resin developed by Johns-Manville for use as chromatographic packing. As one of the Chromosorb "Century Series," it has intermediate polarity. With proper handling, it is stable to 250° C and provides efficient separation of aqueous mixtures containing formaldehyde, acetylene from lower hydrocarbons, and most gases and organic compounds in the boiling range up to 200° C. For more specific information, write for our bulletin FF-194A. Johns-Manville, Box 1960, Trenton, New Jersey. Chromosorb 105 is also available in Canada and overseas. Cable: Johnmanvil.
Johns-Manville JM Chromosorb is a Jshns-Marwille registered trademark for its brand of products developed for use as support material or adsorbents tor gas chromotography.

Analytical Chemistry in Curriculum
I am not so much concerned in w h a t d e p a r t m e n t analytical chem istry is t a u g h t in t h e colleges and universities. Suffice it to say t h a t there should be an analytical ap proach to chemistry which is not p a r t of t h e traditional physical, or ganic, or inorganic experience of a student, and t h a t this approach must be t a u g h t somewhere in t h e curriculum, whether in the t r a d i tional departments of science or in some of the more recent interdisci plinary departments such as en vironmental sciences, pollution, space sciences, and materials sci ence. T h e important thing to re alize is t h a t the analytical chemist is close to the head of t h e list these days when one talks about "rele v a n c e " ; his research can be highly significant.
Industrial Analytical Chemist
In industry the analytical chemist m a y h a v e to become more mobile and less conservative t h a n he has been in t h e past. As we h a v e seen, questions of meaningful analytical measurement are holding up solu tions t o m a n y of the really critical national problems of our time. If a steel company or an oil company does not appreciate or understand the significance and contribution of an analytical chemist, then perhaps t h a t analytical chemist should search elsewhere—in pollution or in health—to m a k e his contribu tions and to gain his satisfactions. Let me be very definite, however, t h a t when I talk about analytical chemistry as a profession, I a m not talking about a routine function t h a t can be taken over by a high school technician, or by an a u t o mated analyzer. W i t h t h e com puterization and automation of m a n y aspects of analytical chemis try, there undoubtedly will be some positions previously held by a n a lytical chemists which now can be delegated t o technicians. On t h e other hand, as analysis becomes more automated and computerized, the demands on t h e analytical chemist himself become much greater. I t is t h e analytical chemist who must interpret t h e d a t a t h a t
