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。

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.
