Abstract
A multiple chamber sample holding cartridge 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.
