XRF spectroscopy

The setup applies Fe-55, Cd-109 and Am-241radioisotopes as primary exciting source, high energy resolution horizontal and vertical Si(Li) detectors and a multipurpose stage for positioning the archeological object |
Portable XRF spectrometer for “in situ” applications

The AMPTEK MINI-X X-ray tube is combined with the AMPTEK X-123 XRF spectrometer or with AMTEK XR-100CR Si-PIN X-ray detector and MCA-8000A multichannel Analyzer. Radioistopes Fe-55, Cd-109 and Am-241 also can be used as primary exciting source |
Non-destructive XRF and PIXE analysis of objects of art and archeology
A suspicious Géza Mészöly painting entitled “Washerwomen at the Lake Balaton”: The detection of the presence of titanium in white spots of a painting provided scientific basis to decide that the painting was a fake.

A strongly disputed “Csontváry” painting: Previous studies indicating the presence of Ti could not be confirmed.


The Cambodian bronze “Buddhist Goddess” sculpture: The External-beam PIXE studies revealed “Goddess” had an iron rich core covered by a bronze layer. Sculptures of similar structure came frequently to light in Egypt, but no indication was found till now that this technique was known in the Far-East, too.

Food contamination
The fast screening of food contamination by PIXE and XRF requires no additional chemical procedure; the sample preparation protocol is very simple.
Pb content of commercial wine products
The permissible level of the Pb content in wine varies in the range of 200–300 μg/l in different countries. These values are below the detection limit for standard PIXE spectrometry. IA protocal was developed to lower the detection limit of PIXE without introducing any additional chemical steps and detection limit of about 50 ppb was finally achieved. Comparing this value to the permissible levels, this simple and fast technique can be used for screening purposes.

Screening the Pb contamination of the red pepper:
A very powerful commercial protocol was developed for screening the Pb contamination the commercial red pepper products.
