Evaluation of Plastic Materials Analysis of Polymer Additives Using LCMS
The various types of additives added to polymer materials and products serve an important function that can determine that
product's performance. For example, for the same type of polymer, the formulation of additives can vary depending on the
brand or grade. This means that the information obtained from analyzing additives can be very important for market research or
product development.

Features of Shimadzu LCMS-2020
Liquid Chromatograph Mass Spectrometers
Evaluation of Raw Materials ▪ From HPLC to UFLC

In addition to speed and separation capabilities, ultra fast LC (UFLC) succeeds in
offering both higher precision and expandability than possible with conventional
high-performance LC (HPLC) systems.
▪ Ultra Fast Speed
To achieve overall faster processing speeds, the LCMS-2020 offers not only faster

analysis, but also faster sample injection speeds and fully automated analytical
functions.

Even though the LCMS-2020 is ultra fast LC, it provides very high injection
reproducibility. It also offers unrivaled carryover suppression, which is critical for
LC/MS analysis.
Product Information Using these features allows easily confirming the elution of components based on the
▪ Extensive Expandability
In addition to ultra-fast analysis, the system also offers the flexibility to be used
for many other applications as well, such as normal HPLC or semi-preparative LC.
