| Abstract: | Summary Several heterocyclic compounds have been investigated by HPLC on RP-8 and RP-18 with methanol-water mixtures as mobile phase.
The chromatographic systems developed showed good selectivity for determination of azines and diazines. Pyridine and quinoline
have been determined in environmental samples and in food. Samples for analysis were preconcentrated by solid phase extraction
on-column with octadecyl silane packing. |
