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...
