XRF Analysis

Hand–Held XRF spectroscopy method has been commonly used for Positive Materials Identification / Alloy Verification (PMI/AV), scrap sorting, Restriction of Hazardous Substances (RoHS/WEEE) etc. Many elements in an atomic number range of 12Mg–92U can be detected non-destructively and quickly in almost all kind of materials (metals, ceramics, polymers, composites etc.) in % or ppm level by means of XRF spectrometer. Fast measurement (2-3 sec) for standard alloys (22Ti–92U), automatically extended times (10-30 sec) for alloys containing light elements (12Mg–22Ti).




Positive Material Identification (PMI)

Positive Material Identification (PMI), so called Allow Verification (AV), can be described as practical, rapid, non–destructive, reliable, and economic control and verification processes for determination of the chemical composition of materials.



Common PMI/AV spectrometers are X–Ray Fluorescence (XRF) and Arc/Spark–Optical Emission Spectrometer (OES) because they are portable, practical, rapid and reliable devices.






In order to protect the environment and human health, it is aimed to limit use of hazardous substances such as mercury, lead, cadmium, chromium VI in electrical and electronic equipment. Within the framework of technical principles, it is ensured that the waste of electrical and electronic goods is recycled in an environmentally friendly manner.




In the event that these hazardous substances are below the limit values ​​stated in the Regulation on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment an published in the Official Gazette dated 30.05.2008 and numbered 26891, the manufacturers may declare RoHS certificate and submit their product to the market. In order to obtain RoHS certificate, firstly, the final product is analyzed in a laboratory. The analyzes are carried out by pre-treating the final product with one of TS EN 62321 standards.


For hazardous substances, the limit values​​ are given below:

Mercury – %0,1

Cadmium – %0,01

Lead – %0,1

Chrome VI – %0,1

PBB – %0,1

PBDE – %0,1
