Abstract
A continuous flow analysis (CFA) is a relatively new ice core analysis method deployed worldwide nowadays. This method allows measuring geochemical and gas concentrations in the ice core samples with ultra-high resolution in depth (age) domain. Different modifications of the CFA experimental setups were built in many research centers dealing with the ice cores and paleoclimate studies. Here we provide a brief history of the method, a description of a typical CFA setup. We analyze the advantages and disadvantages of a setup and propose some ways to solve current technical issues. We show the main principle of the first Russian CFA setup, which is to be built at the Climate and Environmental Research Laboratory, AARI, in order to measure a concentration of atmospheric dust particles and methane in the old atmospheric Vostok ice core.
