LIMITATIONS OF GAS CHROMATOGRAPHY-SINGLE QUADROPOLE MASS SPECTROMETRY IN THE IDENTIFICATION OF COMPOUNDS MIGRATING FROM FOOD CONTACT MATERIALS

摘要

Plastics are commonly used for food packaging. From these plastics potentially hazardous compounds can migrate into the food. It is difficult to establish the chemical structure of migrated compounds especially for the non-intentionally added ones. They are often detected with GC-EI-Q-MS and identified using NIST database without any further confirmation [1]. But to what extent can such results be confirmed?
