“…Different techniques have been used for routine analysis of environmental samples. In recent years gas chromatography combined with mass spectrometry (GC/MS) [1][2][3] has become a method of choice. The method gives useful structural information of the oils in question and is usually successful in characterizing the sample.…”

“…11,[24][25][26][27] A extração de BTEX da amostra por headspace (HS), acoplado ou não a um sistema de microextração em fase sólida (MEFS), seguida pela análise com cromatografia a gás, é o modo mais utilizado para avaliação desses compostos em água. [4][5][6][7][8][14][15][16][17][18][19][20][21][22][23] Isso se dá principalmente devido aos baixos limites de detecção obtidos com essas técnicas, da simplicidade do ponto de vista instrumental, além de que os procedimentos dispensam o uso de solventes extratores e manipulação excessiva de amostra. A eficiência dos métodos de extração por HS ou MEFS sofre a influência de alguns parâmetros experimentais, tais como salinidade, temperatura, tempo de extração e proporção entre as fases.…”

“…SPME is based on extraction of analytes by a thin polymeric film coated to a thin quartz rod (fiber). SPME has been applied to the analysis of different petroleum-originated water pollutants including petroleum fuel contamination [3], polycyclic-aromatic and aliphatic hydrocarbons [4,5], bioavailable petroleum hydrocarbons [6] and gasoline range hydrocarbons [7].…”
