Development and Validation of Gas Chromatography-Triple Quadrupole Mass Spectrometric Method for Quantitative Determination of Regulated Plasticizers in Medical Infusion Sets

Figure 3

Fragmentation pathway of diisononyl phthalate (DINP) in the MRM mode. A similar fragmentation pattern is found for the other target phthalates. The dominant fragmented ion of m/z 149 in phthalates is able to distinguish among different alternative plasticizers, such as bis(2-ethylhexyl) adipate (DEHA).
