What Services Do We Offer?
We provide comprehensive mass spectrometry analysis services that cover all stages of polymer and materials research, from basic research and product development to industrial applications. Our services include:
Polymer Structure Characterization
We use Liquid Chromatography-Mass Spectrometry (LC-MS) and High-Resolution Mass Spectrometry (HR-MS) technologies to conduct both qualitative and quantitative analyses of polymers. By precisely determining the monomer structure, molecular weight distribution, and chain length distribution, we help clients gain in-depth insights into the chemical structure of polymers.
Polymer Component Analysis
Using Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS), we analyze additives, solvents, impurities, and degradation products in polymers. These analyses help assess the stability, safety, and performance of polymers in various environments.
Polymer Molecular Weight and Distribution Analysis
With mass spectrometry technology, we can precisely measure the molecular weight distribution (MWD) of polymers, which is crucial for evaluating the physical properties and processing performance of polymers. Using instruments like LC-MS/MS and MALDI-TOF MS, we provide high-precision molecular weight distribution data.
Polymer Degradation and Aging Studies
The application of mass spectrometry in polymer degradation and aging analysis allows us to study the aging process of polymer materials under different environmental conditions. This provides valuable data to support product stability design and lifespan assessment.
Material Performance and Functional Analysis
We combine mass spectrometry with other techniques (such as infrared spectroscopy and nuclear magnetic resonance) to conduct functional characterization of materials. Whether it is conductive materials, optical materials, or biocompatible materials, we can provide comprehensive performance analysis data.
