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.

Samples of orange juices were evaluated according to standard criteria in Code of Practice and compared with standard RSK values (Richtwerte und Schwankungsbreiten bestimmter Kennzahlen). In 15 orange juices, the content of chlorides, total acidity, volatile acids and ammonia did not exceed values in Code of Practice. It was found that samples F and K (66.30 g/dm3 and 57.65 g/dm3) contained more glucose than is allowed by Code of Practice. Juices G and K did not exceed RSK values for the D-isocitric acid content (103.68 g/dm3 and 109.96 g/dm3). Criterion according to citric and D-isocitric acid ratio corresponded to the normal values in 100% orange juice in samples G, K, L and also in 12% orange nectar P (69.3; 118.6; 51.4 and 72.3).

W pracy przedstawiono wyniki badań zawartości wybranych kationów i anionów w wodach mineralnych, dostępnych w województwie mazowieckim. Uzyskane wyniki porównano z danymi deklarowanymi przez producentów tych wód. Badaniu poddano wody: Bonaqua, Cisowianka, Mazowszanka, Krynica Zdrój, Arctic, Czantoria, Naturalna woda mineralna Lider Price i Żywiecki Kryształ.
