Evaluation of Plastic Materials Analysis of Additives in Polymer Extract Using LCMS-IT-TOF (Part 1)
An organic solvent (in this case, THF/
MeOH = 1/1) was added to a known
quantity of polymer beads. The samples
were then sonicated and the supernatant
was extracted and directly analyzed by
an LCMS-IT-TOF system. Measurement

Of the six types of additive peaks
observed, the below structural prediction
was performed for peak B.

n
The smaller the m/z number, the fewer the number of candidates. Using MS analysis allowed the structural predictions to be narrowed
down.
