Tip of the Month
Temperature stabilization for the S-Mobile system
The S-Mobile is a small compact analyzer that can easily be transported to the job site, when the task calls for fast, real-time, high quality results in the field.
This powerful 50kV, 50 Watt portable X-ray analyzer is capable of rendering sensitive and accurate analysis, similar to laboratory class analyzers.
The fact that the S-Mobile spectrometer can be transported to the job site in a vehicle requires paying attention to the temperature in the vehicle, since in hot weather the temperature can rise to extremely high levels. Prior to starting work on the system, it must be cooled down to a maximum temperature of 25 ͦC. If the temperature is higher, the air conditioning must be switched on, or the system must be cooled down in the shade, in order to protect the X-Ray tube and the system.
The S-Mobile spectrometers are the perfect answer for the job due to their connection to the car’s battery and detachable shock absorber that protect the analyzer during transportation. These functions are also optional in our bench-top analyzers, which makes them the perfect solution for a strong and powerful onsite analyzer.

Quantitative Analysis of Black Sand
A quantitative analysis of Black Sand was performed on samples from various worldwide locations. The analysis was made on a series of samples using Xenemetrix’s EDXRF S-Mobile analyzer and the Standard-Less Fundamental Parameters method. The results of one sample are shown below.
The analyzer was equipped with a Rh-Anode X-ray tube, 50 Watt and several tube filters. The acquisition time was 300 seconds for each sample. In this case, it was decided to place the samples loosely in sample cups. Alternatively, when using a certified standard or if a comparative analysis is required (between different samples), it is recommended to use a mixer-mill in order to reduce particles size, and to then prepare a pressed pellet.
A typical XRF spectrum is demonstrated in Figure 1; Fe is the major peak, Ca, Mn and Ti are also presented (concentrations in wt% are shown in Figure 2).
This Iron Ore application is just one example of how the fast and reliable EDXRF quantitative analysis can be used as a primary method. Good results were achieved even without any standards definition, and there is no need for sample preparation. Using one or a few certified standards may easily result in higher accuracy. For better repeatability, an easy and very common technique of milling and pressing is suggested.
