Supercritical fluid extraction can experience problems of prolonged extraction times and undesired elution of target components of a trap sample. To resolve these problems, a sample is stored in a container () disposed upstream of a back-pressure control valve (). A mixed fluid of carbon dioxide in a supercritical state and a modifier is introduced into the container, and a component contained in the sample is extracted. The extracted component is introduced into a trap column () together with the carbon dioxide and the modifier and collected in the trap column. The trap column is loaded with polymer beads as a filler to securely collect an extracted component in the trap column, even when the modifier in the supercritical fluid is increased.
