New from this X-ray fluorescence analyzer.
A new and unique pulse processor gives our SPECTRACE™ analyzer guaranteed resolution of 150 eV —the best ever achieved in an energy-dispersive X-ray fluorescence analyzer. This resolution, coupled with peak shifts no greater than 3 eV at maximum count rate, lets you detect light elements more reliably and quantify them more accurately. The spectrum at left above shows an actual peak separation using the new pulse processor. That at right, with overlapping peaks, was made using a conventional processor in the same analyzer. SPECTRACE 440 can make automatic unattended analyses of up to
40 samples —solids, liquids, powders or deposits on filter paper. Makes qualitative and quantitative analyses of all elements from Na to Pu. Handles samples from 1 mm in diameter to a foot high. Has superb sensitivity, repeatability and long-term stability. Our applications laboratory and engineering group will work with you to help solve your analytical problem. That way you know you'll get the results you want after your SPECTRACE is delivered. Over 50 SPECTRACE analyzers are now in use. And we'll give you the name of every single user — because we know every one will give you a favorable report. One thing they'll report is the service they get: personal instruction, an applications school, software school — and follow-up visits just to make sure you're getting the most out of your SPECTRACE.

1198 A • ANALYTICAL CHEMISTRY, VOL. 5 1 , NO. 12, OCTOBER 1979
1st International Workshop on Trace Element Analytical Chemistry in Medicine and Biology Neuherberg, Germany. April 27-29, 1980. The general theme of the 1st Workshop is "the essential trace elements." The Workshop will consist of a series of invited papers on specific problem areas each followed by an extended discussion period in which all participants will be invited to take part. Short contributed papers are also solicited. The 1st Workshop will share a joint session on April 29 with the conference on "Biochemische Analytik." Abstracts of papers intended as contributions to the discussions must be submitted in English to the Organizing Committee by Nov. 30. They must not exceed one typed page, double spaced. The abstracts will be subjected to refereeing. Full manuscripts of accepted papers must be submitted by March 30, 1980. For more information, contact: Dr. P. Schramel, Gesellschaft fuer Strahlenund Umweltforschung PhysikalischTechnische Abteilung, Ingolstadter Landstrasse 1, D-8042 Neuherberg, F.R. Germany
