Abstract: PROBLEM TO BE SOLVED: To shorten time required for supercritical fluid extraction and analysis of natural fats and oils such as neutral oil and to lessen the loss components of a specified material such as soybeans and other fatty seeds. SOLUTION: A sample cartridge 30 is divided into chambers 104, 105 by a thin film 119. When the sample cartridge 30 is pressurized, the thin film 119 is ruptured. The sample holding cartridge of plural chambers is used together with a supercritical fluid extractor 10. In this way, materials held in the chambers are mixed with each other. A method of measuring neutral oil and loss of oil of soybean and other fatty seeds by supercritical fluid extraction is performed by the sample cartridge having two chambers.

Abstract: A multiple chamber sample holding cartridge (30) is used with a supercritical fluid extractor that causes membranes dividing the cartridge into chambers to rupture upon the pressurization of the sample cartridge, thereby allowing the intermixing of materials contained in the chambers. The neutral oil and loss determination of soybean and other oilseed oils by supercritical fluid extraction is efficient with this two-chambered sample cartridge.
