This paper expounds the development and preparation process of the acidolysis hydrocarbons standard

sample for surface geochemical exploration. Based on tests on the uniformity and stability of the acidolysis

hydrocarbon standard sample, the authors can guarantee that the standard sample is in line with the related

requirements. Through quite a few statistic analyses of analytical data on the acidolysis hydrocarbon standard

sample, the authors determined its value and uncertainty. The preservative conditions and term of validity of the

standard sample are fixed on the basis of relevant experiments.
