SPLITLESS INJECTION OF LARGE VOLUMES OF AQUEOUS SAMPLES - FURTHER EXPERIENCE - EXPERIMENTS ON ANALYZING TRIAZINES BY DIRECT-INJECTION OF DRINKING-WATER

Conditions were optimized for the introduction of large volumes of dri nking water by splitless injection with vapor overflow, experimenting with the determination of triazines. No co-solvent was added, and the maximum injection volume was 400 mu l. A vapor outlet beyond a coated precolumn was used to discharge water vapors released belatedly from t he packing. Using alkali flame ionization detection (AFID), detection limits were around 0.5 mu g/l.
