The membrane suppressor: a historical perspective

The membrane suppressor for ion chromatography was first demonstrated in 1971. However, development of the membrane suppressor was delayed by the ease of preparation and ruggedness of a suppressor column. By 1981, a practical membrane suppressor had been developed but its excessive band broadening characteristics were not compatible with improved columns that were then being developed. The packed membrane suppressor solved the band broadening problem by 1982.
