A high sensitive EDXRF analyzer is made up with a double exciting apparatus including low energy X-ray tube and isotope source
and an electrically cooled Sin-PIN detector. The analyzer is characterized of high en-ergy resolution and low detection limit. Heavy metal contents in soil of the Panzhihua region were analyzed by the EDXRF analyzer. The results show that the contaminated soil was mainly distributed in the industrial and mining area.
