Abstract:

The full extraction of glaciological chemical information preserved in ice core has been a bottleneck restricting the development of ice core analytical technologies.Previous discrete sample preparations limit the numbers and the speeds of the samples and the samples are prone to be contaminated and destroyed during the preparation resulting in the loss of important information.CFA(Continuous Flow Analysis)has solved this problem successfully and become one of the most popular preparation technologies of ice core sample.This paper summarizes the present conditions and demonstrated the application of CFA used in the analysis of ice core sample analysis in polar region in recent years.At last the prospect of CFA is also described.
