NEW PRODUCTS Quantitative Television Microscope A new quantitative television micro scope provides an effective instrument for rapid, objective, accurate, and re producible measurement of inclusion, grain size, phase proportion, and size distribution. The instrument consists of a conventional microscope fitted with a beam splitter below the eyepiece so that the image is passed both into the eyepiece and into a television camera. The Microscope Monitor presents a normal image, while the Selector Moni tor displays the output of the selector unit by outlining the leading edges of grain boundaries or, for inclusions, by showing in black each area that is ac tually being counted. This signal is passed to an indicating unit which dis plays, on a meter, either the average grain size or the percentage area of inclusions or any other phase. This instrument is made by Metals Research, Ltd., 91 King St., Cambridge, England, and marketed in the U. S. by JarrellAsh Co., 590 Lincoln St., Waltham, Mass. 02154. 431

Macroprobe Attachment for X-Ray Spectrometer
Circle No. 169 on Readers' Service Card
A macroprobe attachment for the company's vacuum x-ray spectrometer enables the analyst to work with beam diameters in the range of 50 to 1000 microns. This permits the qualitative and quantitative analysis of small sam ples and selected areas of larger sam ples. The device accepts samples up to 2 inches in diameter; any sample area within V 2 inch of the center may be studied. A 70X monocular is used to position the x-ray beam. This mac roprobe attachment will operate in vacuum, air, or gas atmospheres and will determine all elements in the nor mal fluorescent range.

Sud'n with its super wetting action is unmatched in cleaning power and rinseability.
Scanning Microanalyzer
Sud'n can be used with complete con fidence in any cleaning application where optimum results are essential.
The SEM2 scanning electron probe microanalyzer includes a specimen turret with 6 specimen holders taking samples of up to 0.5 inch cube of ma terial; micrometer x-y shift controls giving complete coverage of the speci men surface; a fully automatic camera for photography of x-ray and electron images; and an optical microscope with a two-position objective changer operat ing in the vacuum. The finely focused electron probe gives an electron picture resolution of better than 0.5 micron,
