Abstract
A system for pressurized liquid extraction of solid samples including quick-connect, threadless columns for holding the solid sample is disclosed. A pressurized liquid extraction (PLE) module continuously performs extraction on the solid sample to yield liquid sample. The quick-connect columns include a threadless, cylindrical tube and end cap assemblies, which are structured and arranged to provide a tight interference fit with the inner surface of the annulus of the column portion and with top and bottom cup rings.
