S2 PUMA - Energy-Dispersive X-Ray Fluorescence (EDXRF)

Energy-dispersive X-ray fluorescence (EDXRF) with the S2 PUMA provides everything needed to track and measure elements in samples, irrespective of the environment or industry where it is used. The superior power of the S2 PUMA LE is attributed to the different kinds of elements covered by the method, ranging from very lightweight elements such as C, to heavy elements such as U.

HighSense™ is integral to the unparalleled analytical performance of the S2 PUMA. The direct excitation beam path of the instrument ensures complete utilization of the 50 W power of the X-ray tube.

The improved excitation of every element in the sample is guaranteed with up to 50 kV voltage. The high-countrate, high resolution XFlash silicon drift detector (SDD) further improves the performance of the instrument and records sample spectra in HD mode.

Added to that, the distances between the sample, the X-ray tube, and the detector is even shorter than ever before, thanks to the all-new instrument X-ray optics. This leads to higher accuracy, improved detection limits, and shorter measurement times.
