Overview

Multi-element Analysis from Carbon (C) to Uranium (U)

Leading the performance class in Energy Dispersive X-ray Fluorescence (EDXRF)

Unrivalled analytical performance with XFlash Technology

The S2 RANGER performs multi-element analysis from Carbon (C) to Uranium (U) from 100% down to the ppm-level in solids, powders or liquids with little or no sample preparation. Unrivalled analytical performance is ensured by using the highest power in direct excitation geometry.

 

The award-winning XFlash silicon drift detector technology, now available in its new generation XFlash V5, provides best energy resolution with highest count rates. The new XFlash V5 offers a larger active detector area which results in shorter measurement times and better detection limits. This unique combination of excitation and detection power guaranties good element separation, low detection limits, highest precision and best stability.


Technical Details

50 watts of pure XRF power

The S2 RANGER applies up to 50 watts of X-ray power directly to the sample. This comes with the following advantages:

  • No need for moving parts such as primary optics or monochromators
  • Elements at very low concentration levels are excited
  • Higher intensity sets the stage for maximum precision

Award-winning XFlash technology

Thanks to Bruker’s outstanding XFlash detector the S2 RANGER can fully exploit the entire output of the 50 W X-ray tube and can convert this into stability and sensitivity. Owing to its Silicon Drift Detector (SDD) technology, the XFlash is empowered for maximum count rates and the best possible energy resolution:

  • Reliable results are facilitated by high count rates very fast
  • High count rates minimize statistical errors and lead to very accurate results
  • Optimal energy resolution permits different elements to be clearly separated and guarantees that even traces can be detected alongside the main components
  • Due to Peltier cooling, no liquid nitrogen is required for cooling; this minimizes inconveniences and significantly reduces operating costs

Reduced to the max – S2 RANGER

The small sample chamber of our S2 RANGER has three crucial advantages:

  • Short beam path means maximum intensity at the detector
  • Fast evacuation with the integrated vacuum pump ensures high sample throughput
  • In the case of liquid samples, only the sample chamber needs to be filled with helium, thereby cutting operating costs

TouchControl™ – Easy-to-use energy dispersive X-ray fluorescence spectrometry (EDXRF)

The S2 RANGER is performing elemental analysis in an innovative new way. Measurement jobs are quickly defined and started with minimal operator input using TouchControl™, the Bruker AXS proprietary touchscreen user interface. No training or expertise is required to achieve precise results from the very first day. The results display can be exactly tailored to your application and quality control limits are indicated by the traffic ligh colors red, yellow, and green.

The combination of the unique TouchControl™ with SPECTRA EDX provides full analytical flexibility with powerful tools. It keeps the setup of calibrations and applications as simple as possible by suggesting optimized measurement conditions. The universal calibration EQUA ALL enables you to obtain standardless results immediately.


Application

Determination of Low Sulfur in Automotive Fuels and Petroleum Products

In the refining process, sulfur concentrations are reduced from several percent in crude oil to low ppm levels in gasoline. This reduction requires close process control. To ensure and control petroleum product quality, sulfur analysis is also critical along the supply chain in pipelines, tank farms and customs.

The S2 RANGER with XFlash® SDD technology is the perfect match for the determination of low sulfur concentrations in automotive fuels and other petroleum products. Measurement reproducibility and long term stability data are excellent, showing how the S2 RANGER exceeds international standards for sulfur control.

Rapid process control by EDXRF with the S2 RANGER in cement

In the cement industry, production steps must be monitored closely on a daily basis in order to meet high demands on composition uniformity and overall product quality. In cement manufacturing, the S2 RANGER is well-suited as a supplementary system for process control.

The energy resolution and pulse processing performance of the XFlash®detector enable the S2 RANGER to measure not only the usual cement compounds in pellets but also allows it to directly calculate cement modules, such as the Bogue compounds, C3S, C2S, C3A, and C4AF, and the ratios LSF, SM, and AM.
