Abstract:
OBJECTIVEHeadspace solid-phase microextraction (HS-SPME) was used pre-concentration procedure for the determination of tetrahydrofuran in urine by gas chromatography with hydrogen flame detector.
METHODSSeveral parameters controlling SPME was studied and optimised: SPME fiber, extraction time and extraction temperature, desorption time and desorption temperature.
RESULTSUnder optimal conditions, the correlation coefficient was 0.9998 and good recoveries (range from 93.0% ∼ 100.8%) were achieved, the detection limit was 0.5 µg/L.
CONCLUSIONThe method can be applied to the determination of trace amount of tetrahydrofuran in urine.
