///Organic analysis has been applied to geological survey in China in recent yeas. With the shifting of the focus of geological survey from merely “resources” to “both resources and environment”, organic analysis has played a more and more important role in the investigation of water resources, soil resources and environmental ecology. In 2008, the analytical team led by Prof. Rao Zhu took part in drafting and verifying NationalRegulations on Wenchuan Water Quality (water quality determination of putrescine, cadaverine, spermidine, spermine and histamine―high performance liquid chromatography method, GB/T 21970-2008), Melamine Measurement (rapid determination of melamine in raw milk―high performance chromatography method, GB/T 22400-2008), which evidenced the effectiveness of this analytical method and its value to society.
