Determination of low molecular weight organic acids collected on silica gel air sampling tubes by using ion-exclusion chromatography / Minoo Hekmat and Roy G. Smith
Sumario: 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
