B. There was big news all over the internet that the Ponkan oranges that were imported from one of our neighboring counties are heavily contaminated with pesticides. Your lab was asked to analyze these samples using a gas chromatographic procedure. 7. Some samples do not show any signal for the pesticides, your boss told you to use a Solid-Phase Microextraction (SPME) for the extraction procedure. Explain how SPME works and what are the advantages of using this over the liquid-liquid extraction method.
