PROBLEM TO BE SOLVED: To enhance the separation precision of many kinds of chemical components contained in a sample. SOLUTION: The concentration separator includes a cooling gas pipe 3 for directly ejecting a cooling gas to a concentration pipe 2 from the outside of the concentration pipe 2, an infrared lamp 4 for radiantly heating the concentration pipe 2 cooled by the cooling gas, a cooling gas pipe 8 for directly ejecting the cooling gas to a separation pipe 7 from the outside of the separation pipe 7, an infrared lamp 9 for radiantly heating the infrared lamp 4 and a control device 12 for controlling not only the ejection of the cooling as to the separation pipe 7, into which the chemical components dissociated by the radiant heating of the infrared lamp 4 are introduced, but also the radiant heating due to the infrared lamp 9 to rapidly change the temperature of the separation pipe 7 stepwise.
