标准摘要
[中文适用范围]： 本文件规定了采用原子荧光光谱法测定经密闭微波消解法前处理的原油中砷含量的方法。 本试验方法的精密度声明是通过实验室间研究确定的，适用于砷含量在0.35 mg/kg至3.57 mg/kg之间的样品。本试验方法也可用于砷含量更高或更低的样品，但未确定此范围以外的精密度数据。 [外文原描述]： This document specifies a method for the determination of arsenic content in crude oil pretreated by a closed microwave digestion method by atomic fluorescence spectrometry. The precision statement of this test method was determined in an interlaboratory study and is valid for samples with an arsenic content between 0,35 mg/kg and 3,57 mg/kg. The test method can also be applied to samples with either a higher or lower arsenic content, however, no precision data has been determined at levels outside of this range.
