ANALYST'S COLUMN Industrial instrumentation for process control has benefited immeasurably from all these recent developments. To reap the full benefit, industry must see to it that its design engineers and analytical chemists take advantage of these new tools designed for better process control at lower cost. Most companies selling such equipment have technically trained men who know chemistry and instrumentation so that there is little or no gamble in using such equipment. It is important, however, that the design engineer bring the analytical chemist into the early discussion so that the systems to be analyzed are thoroughly understood with respect to interferences to be encountered and the precision and accuracy required. It is also important to determine at such times what determinations are more economically done by instruments located in the control laboratory, when it is not necessary to have continuous recorded analysis. THKKE are some who feel that by installing automatic continuous analysis their analytical and process problems are all solved. It is true that continuous analysis assures the plant operator that as long as the analysis is within prescribed limits, his product will be satisfactory, and this is worth the price of automatic analytical equipment. It does not follow, however, that when the analysis is off, the operator will know why. I t does indicate that the trouble has developed and perhaps may pinpoint the offending operation. The plant analyst may be required to help find the trouble by chemical or more versatile instrument approaches, and for this reason the plant analyst is more helpful to the plant engineer if he is more than a routine control chemist. K . G. STONE, Michigan State College, has written to us about an accidental finding as follows. I thought you might be interested in the age distribution of academic analytical chemists which I found by accident from a compilation which I made from the 1953 ACS Survey of Faculties, Doctoral Theses, Publications, etc., in institutions which offer the Ph.D. I found there were 163 analytical chemists on the faculties. The age distribution was as follows: 25-30, 12; 31-35, 36; 36-40, 25; 41-45, 21; 46-50, 14; 51-55, 18; over 55, 37. These data show the small numbers trained in the early thirties quite well. We don't like to be reminded about those early years of so-called economic adjustment, but we are encouraged by the fact that this survey shows we have substantial new blood in the profession, and we are encouraged personally by the goodly number above 55.

F&P UItramax * _ SEPARATORY FUNNEL Now — from the laboratories of Fischer & Porter, comes the new F&P-developed Glass Separatory Funnel. With the new stopcock, lubrication and freezing problems are ended. Gone are costly leakages and blowouts during centrifuging. Product contamination is completely avoided.
P L U G OF T E F L O N will not freeze or leak. Natural glazed finish of barrel is less susceptible
Note the unconventional design of the F&P Separatory Funnel. The Ultramax* valve consists of a plug of Teflonf turning on a natural glazed surface of unground, precisely-formed Pyrext tubing. Complete interchangeability of parts, all corrosionresistant, makes replacement easy.
to alkali attack.
Funnel sizes available range from 30 ml to 2 liters, and come in the globe, squibb or cylindrical type. Smaller sizes — 30 ml to 125 ml — are especially adaptable for centrifuging. Cylindrical type, 30 ml, is perfect for vitamin analysis.
