Abstract :

Gas chromatography-mass spectrometry (GC-MS) is a globally used analytical instrument for trace level determination of toxicants/ pollutants in various complex matrices. However, traditional sample preparation methods such as liquid-liquid extraction and solid-phase extraction limit the sensitivity of GC-MS for trace level analysis of toxicants/pollutants as well as hazardous to environment and human health. Modern sample preparation methods such as dispersive liquid-liquid microextraction (DLLME) and solid-phase microextraction (SPME) after being coupled to GC-MS results in a sensitive, selective, economical, environmentally benign and green analytical method for analysis of various toxicants/pollutants such as bisphenol-A, alkylphenols, parabens, trichloroethylene metabolites, amino acids, polycyclic aromatic hydrocarbon metabolites, alkaloids (e.g. quinine), pesticides, pharmaceutical drugs, etc., in various complex matrices such as environmental, biological and food samples. Coupling of SPME and DLLME with GC-MS or GC-MS/MS offers highly selective and sensitive determination of aforesaid analytes after throughout optimization and validation of analytical methods which can be used for routine analysis of analytes in various analytical laboratories.
