【Abstract】 In this paper,the JF-3high resolution coulomb method microwater detector was used for analyzing the content of microwater in propylene,ethylene and 1,3—Butadiene.The content difference of 0.5μg/g could be exactly distinguished when the test value vared from 3μg to100 mg,the detection limitwas 3μg/g,the average RSD was 1.86% with a sample levelof100μg/g,the average recovery was 118%.This method operation easy and rapidly and exactly.更多还原
