PITTSBURGH: More crammed elevators — old friends and a number of New Developments in five major product lines from Jarrell-Ash
OPTICAL EMISSION • Now you can perform routine carbonin-steel analyses in an air-path spectrom eter Steel producers will have a chance to see the Jarrell-Ash Compact Atomcounter at Pittsburgh and examine the carbon-insteel data it generates in an air path spectrometer. Excellent slope down to .03% carbon has been measured (the lowest commercial standard available). Analytical reports describing the pro cedure will be distributed at the JACO Booth. • New High-Speed Digital Readout ties the Compact Atomcounter into any Gen eral-Purpose Computer The 1.5-Meter Compact Atomcounter with capacity to determine up to 72 ele ments and provide sequential digital con centrations at a fraction of a second per element will be shown at Pittsburgh, to gether with one of four new read-outs that can be interfaced to feed into any type of General-Purpose Computer. Cir cle No. 211 on Reader Service Card for full information. • New Low-Cost Direct Reader to be introduced: A brand new 3Λ -Meter, Low-Cost Direct Reader will be ready for the Pittsburgh Show. Literature will be available describ ing the self-contained unit design for a seated operator. It can determine up to 30 elements with high sensitivity, precision and speed. It will operate successfully without the need for temperature control. The price will really surprise you: in the $18,000 ball park. Circle No. 212. • Hydrogen in Steels and other metals determined accurately and quickly A new automatic hydrogen analyzer is now offered by Jarrell-Ash for the fast, precise determination of hydrogen in steel or other metals after pouring. Rugged enough to be set upright on the mill floor, the instrument permits fast determina tions of whether additional heat treat ment is required, whether the heat can proceed to the rolling mill, or whether it has to be diverted for use where high hy drogen is less significant. Circle No. 213. 52 A

ANALYTICAL CHEMISTRY
PHYSICAL SCIENCES • New Fast Spectrograph records 2 millisecond light pulse with excellent quality spectra While the new spectrograph may be used for normal spectrochemical analyses, it is of special interest to the researcher who needs speed. With an effective aperture ratio of f/8.6 the instrument is designed to handle short-duration light sources, and weak or momentary emissions such as those produced by the Jarrell-Ash Laser Microprobe source. It can be used as a spectograph, polychromator or scanning spectrometer. Standard is 1-meter, but 2meter versions are also offered for peak resolution. Circle N o . 214. • For Chemistry and Physics Classrooms — and Industrial Research Labs, i f s the Quarter-Meter Look carefully at the 12-pound QuarterMeter Monochromator that will be fitted with an accessory eyepiece at Pittsburgh to let you view and measure the width of the various spectral lines. It is fitted with a digital wavelength readout dial. Priced under $1000, this unit has become a widely used, quality research tool. Full information by return mail. Circle N o . 215.
ATOMIC ABSORPTION • Versatile new ATOMSORB offers ad vantages of the most sophisticated Atomic Absorption spectrometers — at approxi mately half their price. As the pioneer developer of Atomic Ab sorption in the U.S., Jarrell-Ash is now able to wrap up all the needed features in atomic absorption into this versatile new instrument. Simultaneous warm-up of six hollow cathodes performs either atomic absorption or flame emission — instant switching of gases without hazard, entire spectrum blanketed, operation re duced to push-button procedure. For full information, circle N o . 216. • Low Cost DIAL-ATOM Merely dial the element of choice into position, press a few buttons and you're underway with this compact atomic ab sorption spectrometer that handles large volumes of routine analyses with speed and precision. Flame emission capability —naturally! A t Pittsburgh we'll introduce a new linear readout, scale expansion and other improvements. Still at the same low price. Circle No. 217. • New Mark II Anacomp (Atomic Ab sorption Computer) eliminates the need for working curves Instant digital readings in direct concen tration or absorbance from the new Ana comp. N o more working curves. Calibrate simply by running a few standards and adjusting two dials to equal the concen trations in the standards. Includes both emission and absorption modes. Plugs into any Jarrell-Ash Atomic Absorption Spectrometer. Direct print-out capability. For full information, circle No. 218. • Surprise package of the year: a fully compensated Atomic Absorption Spec trometer: more about it at Pittsburgh!
X-RAY • X-Ray Diffraction Equipment Intensity and resolution in X-ray diffrac tion are requisites for quality work; they
are also the prime features of the JarrellAsh Multifocus X-Ray System. T h e equipment is used for single crystal struc ture analysis . . . X-ray diffraction topog raphy . . . powder diffraction . . . stress analysis . . . and routine quality control. Jarrell-Ash offers a complete line of XRay diffraction equipment, including various types of single crystal cameras, diffractometer, electronic console for data recording, powder cameras, recording microphotometers and X-Ray monochromators. • X-Ray Spectroscopy The new Betaprobe (direct electron x-ray spectrometer) provides quantitative anal yses of the light elements in low and high concentration. By using Κ and L spectra, coverage can be expanded from carbon through uranium on the periodic tables. • New Portable Isotope Analyzer will detect as little as 0 . 1 % of an element, particularly useful in mining and metals industries. Elements ranging from calcium (Atomic No. 20) to tin (Atomic No. 50) can be determined in any type matrix within 10-seconds by this unique detector with radioactive source. Particularly sensitive to Fe, Zn, Cu. Reads-out directly in % concentration. It even has a head that can be laid against mine walls for rapid analysis. See it at Pittsburgh or circle No. 219.
A new X-Ray general catalog is in the making. Perhaps it will be ready for dis tribution at the Jarrell-Ash booth at Pittsburgh. T o receive a copy when com pleted, circle No. 220 on Reader Service Card.
SPECIAL PRODUCTS • Quantitative Television Microscope The JACO Quantimet (QTM) is now found in many metallographic labora tories where it is used to collect data on microstructures, determine grain sizes and inclusion counts. It has proved to be especially valuable in the study of carbide sizes in high speed steels in relation to effects of process variables. It computes percentage areas and particle count — quantifies electron micrographs — in metals, ceramics, petrology, powder analysis, fiber, medicine, biology, timber, and air pollution. See it demonstrated at Pittsburgh or send for descriptive bulletin; circle No. 221. • Look to JARRELL-ASH for your SPECTROGRAPHIC SUPPLIES Jarrell-Ash knows what's needed because we operate our own spec labs — we keep most items in stock for FAST delivery. We have the complete line listed in two different catalogs — one on pure m a terials —one on all the spec supplies you need, from film to electrodes. F o r copies of both catalogs circle No. 222.
