Analysis of trihalomethanes in drinking water using headspace
Jan 01, 2003 · Effect of headspace volume on extraction: extraction time of 20 min at 20°C, desorption time of 4 min at 250°C, THMs: 10 μg/l, 1.4 DCB (i.s.): 20 μg/l, vial: 60 ml, n=2. SPME theory dictates that for high-sensitivity headspace extraction, the volume of gaseous phase (headspace) should be minimized.
