Analysis of Polymer Additives Using the LCMS-8030 Triple Quadrupole LC/MS/MS
Antioxidants, ultraviolet absorbers, flame retardants
and other polymer additives are indispensable for
improving the characteristics and functionality of
polymers. Understanding the types and quantities of
these additives to be used is extremely important to
effectively control the manufacturing process of the
polymers.
Below is an example of quantitative analysis of 14
types of polymer additives using MRM (Multiple
Reaction Monitoring) and the LCMS-8030 triple
quadrupole mass spectrometer.
n MRM Analysis with the LCMS-8030
Conducting MRM measurement with a triple quadrupole
mass spectrometer makes it possible to obtain
molecular structure information while simultaneously
performing quantitative analysis. Fig. 1 shows the
chromatograms of 14 polymer additives. Two additives
were analyzed in positive mode, and 12 were
analyzed in negative mode. Fig. 2 shows the calibration
curves of each of the constituents. Excellent linearity
was obtained for every compound tested.

n Analysis of Unknown Polymer Additives Using the LCMS-8030
Quantitative analysis was conducted for the polymer
additives in a food wrapping material and food
container. THF (1 mL) was added to a pulverized
sample (0.1 g), and this was sonicated for 1 minute.
The supernatant was collected, 1 mL of 5 mM
ammonium acetate was added, and the final mixture
was filtered (0.45 μm.)

chromatograms of the substances detected. The
concentrations of each of the constituents calculated
using the calibration curves of Fig. 2 were determined
to be 49.4 ng/g of Irganox 1010 detected in the food
