Phthalates are used as additives in plastic for many years to make them more flexible. Several phthalates are regulated on a global scale, and several analytical techniques can be used for phthalates analysis. Thermal Desorption (TD)-GC/MS is one of the easiest and most accurate methods for phthalate analysis. Recently manufacturers have switched formulations to include unregulated phthalates. Generally, phthalates are identified using both retention time and MS spectra. However, some unregulated phthalates have similar retention times and MS spectra, compared to regulated phthalates. This is the basis of existing ASTM and IEC methods for regulated phthalates by this technique.
