【摘要】 根据密度、闭口闪点等物理参数选择梅瑞16原油作为天然基体,制备了一种硫质量分数为2.75%的标准样品。按GB/T 15000.3-2008、GB/T 17606-2009标准方法对标准样品的均匀性、长期稳定性、储运稳定性等状况进行了考察,并选择了15家实验室进行了硫含量的定值。结果表明,梅瑞16原油标准样品具有良好的均匀性,长期稳定性超过18个月,可耐60℃的高温储运,且基体与待测样品匹配性好。更多还原

【Abstract】 According to the physical parameters such as density,closing flash point and so on,a reference sample with sulfur content of 2.75 wt% was prepared by selecting Merey 16 crude oil as natural matrix.The homogeneity,long-term stability,and storage and transportation stability of the reference samples are tested,and 15 laboratories are selected for determination of sulfur content.The results show that the crude-oil-matrix sulfur reference sample has good homogeneity,long-term stability over 18 months,and storage and transportation stability,which can withstand the temperature of 60 ℃.Its matrix also has good match with samples.更多还原
