2015/11/25 · Elution times for Phthalates on various Restek GC columns. A commonly used technique for phthalate analysis is gas chromatography-mass spectrometry (GC-MS), which is simple, fast and inexpensive. GC-MS also provides additional mass spectral information and thus serves as an ideal instrumental platform for phthalate identification and quantification.
