Sturdy construction ensures long operating life... simplicity of design permits easy servicing. The new Matheson Potentiometric Chart Recorder Model 8500 also offers solid state circuitry, superior linearity (0.1%) and resolution (0.2%), four ranges (1, 3, 5, 5000 mv. DC), 2 speeds, (1 & 2"/min.). Here's sensitivity and reliability unequalled by any chart recorder in its price range.

SYMPOSIUM ON STANDARD RADIOACTIVE MATERIALS AND THEIR APPLICATIONS

The recorder can be used with the Mass Flowmeter, Dynà-Blender, Chromatograph or any instrument with a 1 to 5000 DC millivolt output. Only Matheson has developed compatible systems for all gases and handling equipment — completely integrated components such as regulators, valves, flow meters, purifiers and generators blended together to form systems that work.

JCC Session on Laboratory Automation

• Starts and stops automatically — whether flow time is 10 seconds or 1000 seconds • Accurate to .02% ± . 0 1 seconds with both rising and falling-level viscometers The Wescan Model 220 Automatic Viscosity Timer measures viscosity up to ten times more accurately than manual methods — while freeing the operator for other activity. It measures flow times up to 9999.99 seconds, at temperatures from —75°C to 150°C. Changes in light reflection trigger the timer by means of photosensors. For details about the way the Model 220 saves time and measures more precisely, write for PB 702.

Laboratory automation is the topic for a special session planned for the 1971 Fall Joint Computer Conference to be held in Las Vegas, Nov., Nov. 15 to 18, 1971. The primary theme of the conference is the use of computers to improve the quality of life. Original papers illustrating applications in chemistry and related areas are being solicited for the session, "Systems and Concepts for Laboratory Automation." This session is being designed to provide a forum for the dissemination of methods and techniques now available and to stimulate new developments. Those wishing to submit papers should first contact either of the session cochairmen: Leonard H. Ponder, American Enka, Enka, N . C. 28728, 704-667-6961, or David L. Schroeder, On-Line Systems, 4721 M c Knight Rd., Pittsburgh, Pa. 15237, 412931-7600 The Joint Computer Conferences are held twice a year under the sponsorship of the American Federation of Information Processing Societies (AFIPS) and encompass the entire information processing field. By including this special session, an opportunity is provided to gain an overall view of computer technology as well as specifics in areas of particular interest. Exhibits will port r a y the impact of modern computer technology in many fields.

Too bad. Set up a gas chromatography system, develop a proper technique and then spoil it with a leaky system. For as l i t t l e as $ 3 1 0 . 0 0 the GOW-MAC Gas Leak Detector will find the leaks in your system and make your chromatography more accurate. Cordless, portable and equipped with a self-contained rechargeable battery and charger, or line operated, the GOW-MAC pin points leaks of inert, combustible, light or heavy gases in hot or cold pressurized systems and in hard to reach test points through use of a stabilized thermal conductivity cell and a self-contained solid-state amplifier. Signals audibly or visually. Single knob for null balance makes operation simple. Sensitivity is 10 -e cc at atmosphere/second of Helium. For Helium or Hydrogen it sees lOppm of gas in static systems. Selected by the United States Navy for testing underwater equipment, the GOW-MAC Gas Leak Detector can help you stop spoiling your accuracy and eliminate costly and dangerous gas leaks in your lab.

Denver Conference on X-Ray Analysis Applications The 20th Annual Denver Conference on Applications of X-E,ay Analysis will be held Aug. 11 to 13, 1971, at the Albany Hotel, Denver, Colo. Technical papers on subjects related to X-rays and their applications will be presented

during the 3-day meeting. The em phasis this year will be on instrumenta tion as applied to diffraction, fluores cence, microprobe, and other related techniques, including developments in automation. Also, general papers on other aspects of X-ray analysis are in vited. Abstracts of papers (three cop ies, about 300 words) should be sent before Apr. 15, 1971, to C. O. Ruud, Conference Cochairman, Dept. of Met allurgy and Materials Science, Univer sity of Denver, Denver, Colo. 80210. Final manuscripts are due July 16,1971.

FOR CHROMATOGRAPHIC ELUTION OR FILLING ZONAL ROTORS With a capacity of 3200 ml/hr, the Model 380 DIALAGRAD Programmed Gradient Pump is especially suited for filling zonal rotors as well as form ing liquid chromatographic elution gradients and similar applications. Almost any two component gradient can be formed by simply setting a series of dials. There are no cams to cut or multiple solutions to mix at estimated concentrations. The shape of the curve is determined by setting eleven 0 to 100% dials which repre sent the initial, final, and nine evenly spaced intermediate ratios. Thisgives 10 program intervals, each of which are automatically subdivided by five linear interpolations to produce a smooth gradient. Calibrated flow rates from 1 to 3200 ml/hr and program durations from 5 minutes to 16 days are set with positive stop switches. The DIALAGRAD will produce linear or curved gradients with equal accuracy and the program will be perfectly reproducible run after run. The instrument takes but a few minutes to program and requires no attention during a program run. For more information, please re quest Brochure DP31.

Sadtler Research Laboratories, Inc.,

3316 Spring Garden St., Philadelphia, Pa. 19104, 215-382-7800, is now market ing a data-retrieval system called IRIS. This infrared information system (pro duced in conjunction with the Univer sity Computing Co.) offers a fast, eco nomical way to identify spectral un knowns. There are about 100,000 coded spectra in the data base which will be added to as other spectra collected are coded. Multiple searches, up to 25 at one time are permitted, helping reduce costs. Bendix Corp., Southfield, Mich. 48075, 313-352-6233, has purchased sub stantially all of the assets of Unico En vironmental Instruments, Inc., a whol ly-owned subsidiary of the Gelman In strument Co. In addition, certain other products, property, and assets of Gelman related to the Unico product line have been bought. The products are related to environmental health and include instruments for the detection, analysis, and measurement of gases, va pors, and particulates, as well as devices for the sampling and monitoring of large volumes of air. The Swedish scientific instrument manufacturer, LKB-Produkter, which is known in the U. S. through its subsidi ary, LKB Instruments, Inc., of Wash ington, D. C , has acquired the Finnish instrument company, Wallac OY. The latter firm makes automatic liquid scin tillation counters and automatic gamma counters, as well as other instruments connected with isotope analysis and radioactivity measurements. Also, a new LKB subsidiary has been estab lished in France. A new program called HELP (Honey well Equipment Leasing Plan) provides for the lease or rental of electronic test ing, measuring, and recording products marketed by Honeywell's Test Instru ments Division in Denver. Honeywell has also announced a 20% reduction in repair and calibration costs for elec tronic test instruments. This service is called Honeywell Plus-20.
