Polymer Characterization Service Based on MALDI-TOF MS

STEMart provides advanced Polymer Characterization Services utilizing Matrix-Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS). This cutting-edge technology allows us to accurately determine polymer molecular weight distributions, end group compositions, and structural characteristics. Our MALDI-TOF MS system offers unparalleled precision in analyzing synthetic and natural polymers, providing essential insights for quality control, product development, and research applications across the polymer and materials science industries.

MALDI-TOF MS works by ionizing large polymer molecules through laser excitation, allowing for their mass-to-charge ratios to be measured in a time-of-flight analyzer. This powerful technique is ideal for determining the molecular weight distribution of polymers, as well as the composition of copolymers and other macromolecular substances. It is widely used in disciplines such as polymer chemistry, materials engineering, and industrial product development, where the accurate characterization of polymer structures is critical.

Leveraging our MALDI-TOF MS technology, STEMart offers a comprehensive suite of polymer characterization services to meet your research, production, and quality control needs. Our team of experts provides precise, reliable data to support the development and optimization of polymer formulations, ensuring your products meet industry standards.
