On-line solid phase extraction-gas chromatography-mass spectrometry ha
s been used for trace analysis of phenols in water samples at the low
ng L-1 level. Phenols have been derivatized by in-sample acetylation p
rior to an automatic SPE-GC-MS procedure. The method was validated wit
h 26 alkyl, chloro and mononitrophenols including 4-nonylphenol and 17
-ethinyl-estradiol. Target analysis was performed by time-scheduled, s
elected ion monitoring. The on-line SPE-GC approach resulted in low sa
mple volume (typically 10 mL), good reproducibility, sensitivity and c
onsiderable saving of reagents, material and manual work.
