X-ray fluorescence analysis is often used for material analysis of fuels or lubricants. As these are usually liquid, they can only be analysed in a special sample container and/or in an atmosphere of pure helium. Thus, the light elements are hardly measurable, at least if they exist in low concentration. Terrachem uses a self-developed and patented method in order to avoid this problem. This method is mainly applied to analyse crude oil, biodiesel and liquid lubricants.
The method is called LiTrap (Liquid Trap). It enables the measurement of liquids under vacuum conditions. Hence, cumbersome container walls and helium are not necessary any more, in total, the method’s detection limit is lowered.
Thanks to our LiTrap method, we are able to detect the “difficult” elements Ca, Mg, Na, K, F reliably and reproducible even in the lower ppm ranges.
The capability of our LiTrap method has recently been demonstrated in a round robin test with renowned partners. In only one measurement run, several parameters can be analysed without difficulty! Therefore, the complicated and expensive measurement with several methods is no longer necessary (AES, ICP-MS and X-ray fluorescence analysis).
Material analysis of Fuels and Lubricants using LiTrap
Do you have a liquid sample to be analysed and the required sensitivity can only be reached under vacuum conditions? Now you do not have to make any compromises!
LiTrap (Liquid Trap) is terrachem’s patented solution.
Further advantages:
- No complex sample preparation through chemical transformation
- The matrix works as a “filter”: particles concentrate on the surface and can be easily analysed.
Material analysis of fuels and lubricants using X-ray fluorescence analysis is completely sufficient!
