ABSTRACT
Isotachophoresis using coupled capillaries (ITP) and ion chromatography (IC) – two analytical procedures
for the determination of anions in atmospheric wet deposition – were compared. Both techniques were
used for the determination of anions in small volume samples of dew, rime and fog deposition. IC was characterized
by lower limits of detection and quantitation. The wide dynamic range of the technique made it suitable
for accurate and precise determination of the analytes in samples of widely different matrices and analyte
levels. No significant differences were observed between the two techniques in terms of time- and labor intensity.
