In programmed runs, substantially higher apparent efficiencies were observed. These
results were obtained in spite of repeated assertions in the literature that efficiency in packed
column su-percritical fluid chromatography has a practical upper limit of 20 000 theoretical
plates. The simultaneous high efficiency and high speed appear to substantially exceed all
previous reports using packed columns and dense fluids.
