<abstract displayLabel="Summary">Ion-exclusion chromatographic separation of organic acids by using tridecafluoroheptanoicacid solution as the eluent and conductivity detection were studied. Air samples were collected on silica gel tubes and desorbed in water. The proposed method was applicable to the separation of formic, acetic, propionic, and butyric acids</abstract>
