HS-SPME for the Determination of Phthalate Esters in Vegetable Oil and Soft Drink Samples

A simple and environmental friendly method using headspace solid-phase microextraction (HS-SPME) determination of four phthalate esters in vegetable oil and soft drink samples were investigated. The extraction temperature, extraction time and desorption time were evaluated by comparing two types of...

The extraction temperature, extraction time and desorption time were evaluated by comparing two types of commercial SPME fibers; polydimethylsiloxane/divinylbenzene (PDMS/DVB) fiber and polyethylene glycol (PEG) fiber. The PDMS/DVB fiber showed better response than PEG fiber. The linearity, limit of detection, repeatability and reproducibility were validated.
