Four Of The Best Reasons For Better Analysis
SPECTROMET* With Baird Associates Spectromet* quality control analysis is possible directly on the production floor. Indicator readings give constant control of the contents of the melt. Sealed optical and electrical compartments provide a built-in laboratory environment. This new instrument is designed for those who have a moderate work load involving no more than six elements in one matrix. Bulletin #42 (to be shown at the Pittsburgh Exposition, March 1, 1955)
3 - M 2 0 " SPECTROGRAPH Baird Associates model 3-M Spectrograph, the first large grating instrument to be used commercially, offers many new refinements which increase its effectiveness. The instrument's modified Eagle mounting of a concave grating is the only one with the flexibility to permit use of the fourth or even higher spectrum. The range of the available spectrum is greater than twice that obtainable by any other commercial concave Spectrograph. The 20" camera gives the greatest wavelength coverage for a single exposure, WITH HIGH DISPERSION, of any standard instrument. Bulletin #32-C

For unlimited value these instruments are the best that are currently available because they are built on VERIFIED PRINCIPLES. + Therefore, they are the most reliable for rapid, large-volume sampling either in research or quality control analysis. They are widely used in the field of metals production and fabrication, in the inorganic and organic industrial chemicals and in related enterprises where the management knows that competitive advantages are to be gained by superior instrumentation.
DIRECT READERS The new features of the 1955 Direct Readers give improved optical stability, more precise monitoring and increased flexibility in spectrum line selection. Both the standard production control type and the research instrument afford stability and precision far beyond the average and enable the quality control engineer to do his best work. The instrument will accommodate as many as sixty photomultipliers providing many variations for complex work loads. Bulletin #34-C
INFRARED The Double Beam 1R Recording Spectrophotometer for 1955 retains in its new design the outstanding features which made operation, control and maintenance rewardingly simple and easy. In addition, its advanced engineering now provides important slit programming for greater reproducibility, a continuous variable speed drive, a two-speed recorder for expanded wavelengths scale, provision for recording wave or linear wavelengths and many other features for greater versatility with speed and accuracy.
