Your Analytical Problem is
DIFFERENT! maker of the broadest line of spectrochemical instruments . . . can meet your special requirements. Matching the instrument with the problem is a Baird-Atomic specialty. For over 25 years, B / A has led the field with the most complete line of emission and infrared analytical instruments . . . has had more experience with different problems than any other manufacturer. Here are a few of the significant "firsts" established along the way: • FIRST high resolution large grating Spectrograph introduced in 1935. • FIRST Direct Reading Spectrometer introduced in 1946. • FIRST Double-Beam Infrared Spectrophotometer introduced in 1947.
Electroanalytical Abstracts The Jmnnal of Electroamilytical Chemistry has initiated a new section which contains abstracts on fundamental electrochemical and analytical applications. Included are electrophoresis and paper electrophoresis. The abstracts will be incorporated with the .Tournai or may be obtained separately, liâtes for the abstracts are $4.00 and may be ordered from Elsevier Publishing Co., 110-112, Spuistraat, Amsterdam-C, The Netherlands.
• FIRST Direct Reader to operate without laboratory control — the SPECTROMET — featuring the exclusive Automatic Optical Servo Monitor — introduced in 1955.
B/A's
SPECTROCHEMICAL
Direct Reading Spectrometers — for fast analysis . . . Chemical composition obtained in seconds — for melting control or for large volumes of samples. Available in two models:
Detroit Anachem Conference Scheduled The Ninth Detroit Anachem Conference, sponsored by the Association of Analytical Chemists, Detroit, Mich., will be held again in McGregor Memorial Conference Center at Wavne
INCLUDES:
Spectromet — Requires no laboratory, can be installed close to melt shop. Special rugged compact construction. Automatic Optical Servo Monitor automatically compensates for movement of spectrum lines due to changes in temperature, atmospheric pressure, shock and vibration. Direct Reader — Versatile model for analyses of many materials — aluminum, magnesium, cast iron, stainless steel, etc. 3-Meter Spectrographs Laboratory — The versatile 3-meter concave grating spectrograph for best trace element sensitivity; highest resolution and dispersion; sharp, clear uniform spectrum lines throughout the spectrum. A modern, convenient-to-use spectrograph for both routine analysis and research investigation.
Chemical Microscopy Course at Cornell A three-week course in Chemical Microscopy will be given at, Cornell University, beginning July 10, 1961. It will include measurements and particlesize determination, quantitative analyses, study of crystals and polymeric materials with the polarizing microscope, physical chemistry of crystallization, optics and photomicrography, and an introduction to qualitative analysis. Enrollment is limited, and should be firm by June 15. Correspondence should be addressed to C. W. Mason, School of Chemical and Metallurgical Engineering, Cornell Universitv, Ithaca, X. Y.
LINE
Research Direct Reading Spectrograph
B/A also manufactures the versatile Spectrosource to provide various excitation conditions, the Densitometer-Comparator for measuring spectrum line intensities, and a complete line of accessories. Research Direct Reading Spectrograph — Combines the versatility of the spectrograph with the speed and precision of a direct reading spectrometer. Permits either photographic or photoelectric measurement. Interchangeable DR heads and a unique electronic slit setting device permit a wide range of direct-reading investigation.
~~ Infrared Spectrophotometer
Write for literature describing B/A's spectrochemical line — or better still, tell us about your analytical problem.
Infrared Spectrophotometers — New Models NK-1 and NK-1A feature the proven B/A optical system — large prism, globar source, sealed bolometer detector. These instruments offer maximum prism resolution and signal-tonoise ratio . . . with the fastest scan speed. Broad line of accessories available.
