Excellent performance for an entire lifetime
Conventional X-ray tubes suffer tungsten evaporation from the cathode filament, causing deposits on the inside of the tube's beryllium window. This results in instrument drift, decreased intensities and longer counting times, particularly for light-element analysis. The ZETA technology in SST-mAX eliminates the classical tungsten cathode evaporation, the major contributor to instrument drift. The ZETA technology ensures that the initial performance is maintained throughout a tube’s lifetime. This results in a reduced need for recalibration, minimizing downtime and expert intervention.
Unprecedented light-element performance and reliability
While light-element performance is enhanced by incorporating thinner beryllium windows in X-ray tube designs, thinner windows are traditionally more fragile and vulnerable to corrosion by sample spillage. The CHI-BLUE coating on the beryllium window is a technology breakthrough that completely eliminates these risks, by providing an hermetic seal and excellent resistance against corrosive chemicals. In contrast to many other existing coatings for beryllium, CHI-BLUE is completely stable at elevated temperatures and under prolonged X-ray exposure, ensuring excellent reliability over the tube’s lifetime.
High overall intensity
The SST-mAX50 has a high overall intensity due to the high emission current (up to 160 mA), the high tube power (4 kW), a close optical coupling with sharp tube nose and the availability of various anode types.
