DO IT Y O U R S E L F . . . WITH BUILDING BLOCKS A little over two years ago the "Building Block" concept of instrument design was announced by Perkin-Elmer. Since that time, the number of optical and electronic instrument components available from Perkin-Elmer for all types of radiation instruments has greatly increased. A complete listing of these components, plus descriptions of some standard types of instruments that have been constructed from building blocks, is found in the Summer 1954 iSSUe Of INSTRUMENT NEWS.

T h e Concept—Under the "Building Block" concept, basic functional parts of an instrument such as source, monochromator, detector, amplifier, etc., are designed as separate units which may be attached in various combinations. Thus, a wide range of instruments for specific applications may be assembled from a few standard components. For example, with standard Perkin-Elmer parts it is possible to construct such instruments as universal spectrometers covering the visible, ultraviolet and infrared regions; microspectrophotometers for the same regions; high resolution, grating spectrometers; and many other instruments which utilize monochromatic radiation. Where necessary, special components can be developed to complete a particular instrument. Among the standard items constructed from building blocks are allwavelength spectrometers, a new Raman Spectrometer, the automatic Multicomponent Analyzer, and a Rapid Scan Monochromator.

Ethylene is becoming an increasingly important raw material in organic chemical processing. And in the production, purification and utilization of this material, process stream control by means of infrared analyzers is also becoming increasingly widespread. In the Spring 1954 issue of INSTRUMENT N E W S f o u r d i f f e r e n t t y p e s of process stream problems involving ethylene production are presented and their solution, with the aid of T R I - N O N Analyzers, is outlined. These problems include: determining ethylene content in feed gas; determining ethylene purity in purification process; determining ethylene concentration on 8 different streams; determining ethylene content in an ethylene glycol plant stream. These are the type of problems for which Perkin-Elmer's Application Engineering Laboratory is equipped t o find the solution. If you have a processing problem, it will pay you to write PerkinElmer t o determine how infrared analyzers may be applied in your plant.

Rapid Scan Monochromator Developed with Building Blocks One of the most novel of the new building block instruments is the Model 108 Rapid Scan Monochromator. The first unit was built for the Army Chemical Center to assist in the study of various types of combustion. Studies of reaction rates, the formation of intermediates and other kinetic problems may also be handled by the new instrument. Any portion of the spectrum may be observed at will. Scan frequency is continuously adjustable from 2 to 125 cycles per second. Photographic accessories for permanently recording the spectra can also be provided.
