Quantex-Ray is a completely com puterized X-ray energy spectrometer system for rapid quantitative ele mental analyses. It's an enormously flexible system, allowing both inter active and automatic operation. In fact, operation can be so automatic that all you do is type one simple command to activate a total analysis. What does Quantex give you? In one, totally modular XES system, Kevex provides: • A powerful, versatile digital com puter, capable of independent and simultaneous operation. It identi fies trace elements and major ele ments and automatically removes Si escape peaks. • Easy-to-use software, including Colby's MAGIC V, FRAME B, Bcnce-Albee, and thin film...all for electron column applications. EX ACT handles X-ray fluorescence analyses. Oxide percents? Yes. • The highest-resolution X-ray detec tion subsystem, featuring the new Kevex Mark V 30 mm 2 detector with 148 eV resolution available. You get higher throughput and more useful data per minute than any other XES system. • Human-engineered control console with interactive color coded video display and printer terminal. You c a n " s e e " t h e a n a l y s i s a s it proceeds — with anomalous data clearly flagged. The bottom line? Printout of qualitative and/or quan titative results. Kevex strongly supports QuantexRay with training, service, applica tions and software assistance. Con tact us for more details about the industry's premier XES system.
