Abstract: An extraction apparatus for extraction analysis of solid material is described, which consists of an extraction column mounted on a frame and a tubular filter holder mounted on the frame beneath the column. The holder is movable in the frame into and out of engagement with the lower end of the column.A multi-port valve is connectable to the lower end of the holder for supply of extraction liquid and flushing liquid to the column through the filter and for withdrawal of extraction liquid and flushing liquid from the column through the filter. The filter holder is removable from the frame for analysis of the solid material remaining after the extraction.
