Development of the Underwater in-situ X-ray fluorescence spectrometry measurement equipment

To avoid and weaken as much as possible the impact which unevenness effect acts on the underwater in-situ X-ray fluorescence spectrometry, an underwater in-situ X-ray fluorescence spectrometry assistance measurement equipment is developed. The equipment is composed of underwater video camera system and angle measurement system, and it is installed on a portable X-ray fluorescence spectrometry probe and is used to underwater in-situ X-ray fluorescence spectrometry. Thus the underwater measurement can effectively select the measuring surface and avoid and weaken the unevenness effect campared with the measurement on the ground. The equipment is installed combined type, and it can be used underwater with a maximum depth of 30 meters, and its angle measurement system can also be used in other places to be measured angle. Experimental results show that: the development of the measuring device solves unevenness effect underwater in-situ X-ray fluorescence spectrometry. (authors)
