Determination of aromatic compounds in Malaysian commercialized petrol using solid phase micro extraction (SPME) coupled to gas chromatography mass spectrometry detector (GC-MSD) / Mohamad Rosdi Muhammad Razali
A method for the identification of aromatic compounds in different varieties of petrol by using solid phase microextraction (SPME) and gas chromatography-mass spectrometry detector (GC-MS) was developed. SPME fiber coated with polydimethylsiloxane (PDMS) was used in this study. The effects of import...
