ARL's N E W PXQ* gives greatest variety of analytical programs
NEW PRODUCTS The manufacturer says the console is a completely self-contained generating unit designed for a wide variety of uses, such as qualitative and quantitative identification of chemical substances, stress tests of solid materials, measurement of crystal sizes, identification of alloy compounds, and the study of various chemical reactions. The console model has a 60-kv. potential at peak current of 50 ma. Shockproof and "rayproof," the unit contains its own stabilized power supply which provides a filtered direct amount of energy to the x-ray diffraction tube. Accessories include a long cylindrical camera for work with powder samples, a short cylindrical camera, a combined flat camera for back reflection, a stereomicro camera for microradiography of MÈÊÈ?

For the fast, simultaneous quantitative measurement of all elements in the 0.35A to 10.2A range, this flexible direct-reading multi-channel x-ray polychromator gives you the maximum amount of accurate, reliable information. You will enjoy economies in time and labor never before possible. The P X Q is the first truly practical instrument to take full advantage of nondestructive x-ray fluorescence principles in spectrography. By significantly widening the wavelength range available for simultaneous analysis, the PXQ offers full coverage above atomic number 11. Sensitivity has been increased. The PXQ is extremely versatile, offering a wide choice of components and simple operation by regular personnel. Rugged design has proved itself in dependable performance. Use the P X Q for fast, routine analysis in process control— convert it to research through use of scanning monochromators. Ask your nearby ARL representative about applying the PXQ to your process or write for full information. Your inquiry will be answered fully and promptly. *Tradc Mark

thin specimens of ore and similar objects, a Guinier camera for examining materials with low reflecting power, and a camera for stress measurement on heavy or bulky pieces. A diffractometer attachment permits the determination of position, intensity, and width of x-ray diffraction lines on polycrystalline materials. The high voltage supply provides for any potential between 300 and 5,000 volts with an accuracy of 0.02%. The recorder is an electronic balance strip chart instrument with adjustable speed. The shock- and rayproof 187-pound table model diffraction apparatus provides a maximum output of 40 ma. at 60 kv. Four windows are available for attaching cameras, which may be operated simultaneously. These have individually timed shutters for each x-ray port. The table unit houses its own high voltage and filament transformers with seven-step 25-to-60 kilovolt power supply. P - 5 , 6, 7
