    摘要: A fractionated sample collection process and device having at least one pressurized chamber used to gather and store liquid samples generated from a flow stream containing a mixture of highly compressed gas, compressible liquid, or supercritical fluid and a relatively incompressible liquid. A bank of multiple collection chambers is secured together in a frame to form a cassette unit. Each collection chamber may house a replaceable liner such as a test tube vial, to hold a fractionated liquid phase sample. After filling with sample, a collection chamber is returned to a clean state and ready for refilling with a new sample by manually or automatically replacing the liner.
