Post-Extraction Losses of Volatile Aromatic Hydrocarbons During Capillary Extraction–HRGC Analysis: A Quantitative Assessment

Abstract  Benzene, toluene, ethylbenzene and o-, m-, and p-xylenes (BTEX), were extracted from aqueous samples by capillary extraction (CEx), a manual form of in-tube microextraction inherently compatible with capillary GC, and analyzed
