A NEW XRF PROBE FOR IN-SITU DETERMINING CONCENTRATION OF MULT I-ELEMENTS IN OCEAN SEDIMENTS
摘要
Abstract
This paper introduces a new X-ray fluorescence probe for in-situ deter mining the concentration of multi-elements in ocean sediments. The probe consis ts of Si-Pin X-ray detector with an electro-thermal colder, two isotope sources, e ssenti al electrical signal processing units and a notebook computer. More than 10 elem en ts can be simultaneously determined at a detection limit of (10~200)×10-6 and precision of 5%~30% without liquid Nitrogen supply. Tests show that the probe c a n perform the analytical tasks under the water at the depth of less than 1000 me ters.关键词
