TRI-CARB LIQUID SCINTILLATION SPECTROMETERS
Î
For counting Tritium, Carbon-14 and other beta emitting isotopes. Provides the most simple and convenient method for precise counting of beta samples that go into solution with liquid phosphors. _• ' Aqueous samples of various types may also be readily counted. Certain materials that are not soluble in liquid phosphors may be counted in suspensions.

AUTOMATIC FRACTION COLLECTORS For precise column chromatography. Provides both time a n d drop counting. Can be furnished for time o p e r a t i o n only at commensurately lower cost. Drops from column fall directly into test tubes. There are no intermediate collecting vessels, glass arms, or funnels to cause mixing, contamination, evaporation, etc. This is important where accurate separations are required or where radioactive tracers are used.

WINDOWLESS AND FLO-WINDOW COUNTERS Both types can be used for Geiger and proportional operation. Windowless Flow Counter, Model 200A, provides m a x i m u m sensitivity for counting solid samples which emit very soft radiations. Has essentially unlimited life. Physical arrangement of sample in chamber makes it possible to achieve full 2 « geometry. Flo-Window Counter, Model 210, features a very thin metalized window of Du Pont Mylar which offers a minimum of obstruction to low energy radiation. Isolates counting chamber from sample. Eliminates static charge, vapor effects, accidental contamination, etc.

ANALYTICAL CHEMISTRY
Accidental radioactive spills can produce serious emergencies. On the other hand, many companies are not equipped to cope with such a situation. Tracerlab, Inc., offers a solution to the problem by organizing several emergency decontamination teams as a service to industry. Based at the company's Houston, Tex., Richmond, Calif., and Waltham, Mass., offices, the teams are prepared to go to any part of the country on momentary notice. Each team consists of a chemist and physicist familiar with radioactive materials, plus a number of skilled technicians depending on the job to be done. In addition to providing necessary instruments, equipment, and personnel for doing such a cleanup, the company can make analyses on biological samples to determine extent of radiation damage to personnel. Tracerlab points out that their experts act in the capacity of disinterested third parties. This is especially appropriate in legal disputes, where expert testimony is needed to settle claims.
Chemical Industries Exposition in New York City The 26th Exposition of Chemical Industries at New York City's Coliseum, Dec. 2 to 6, will feature production of chemicals, chemical processing, and use of chemicals and their reactions in many industries that are basically nonchemical. About 500 exhibitors will occupy four floors of the building in showing new trends in chemicals and equipment. This, according to Ε. Κ. Stevens, exhibi tion manager, will go along with deemphasis of any tendency to display merchandise purely as sales promotion. Scope of the show is intended to cover all phases of industry from initial incep tion to final manufacture of products. Stevens says that special interest will be centered on new construction ma terials, including some of the rare metals and new plastics. Also of interest will be. new instruments for research and control. A special section of the show, the Rocket and Satellite Section, will be sponsored by the American Rocket Society. Emphasis here is placed on chemicals and construction materials as
