The Applied Technical Services Family of Companies (ATS FoC) provides comprehensive size exclusion chromatography (SEC) analysis. Our laboratory delivers reliable, reproducible polymer characterization using advanced chromatography and complementary techniques, offering critical insights into size-related polymer properties.
How Does SEC Support Supplier Qualification and Material Verification?
Size exclusion chromatography supports supplier qualification and material verification by providing precise molecular weight distributions and composition metrics to confirm batch consistency and compliance. Our services identify lot-to-lot variation, contamination, degradation, and verify polymer architecture against supplier claims. Our reports include statistical comparisons, trend analyses, and pass/fail assessments tailored to client specifications. Procurement and quality teams use these data to approve suppliers, monitor materials, and initiate corrective actions as needed. Fast turnaround and traceable results streamline audits, reduce supply chain risk, and increase confidence.
About Our Size Exclusion Chromatography Analysis Services
Our ISO-accredited lab provides precise molecular weight distributions, absolute molecular weight, intrinsic viscosity, and oligomer profiling for synthetic and biopolymer systems. We offer rapid turnaround, secure data delivery, and detailed reports tailored to client needs. Common SEC approaches used in our lab include:
Detection Capabilities
- Multi-angle light scattering (MALS) detection determines absolute molecular weight values across a polymer sample.
- Refractive index (RI) and ultraviolet/visible (UV/Vis) absorbance detection methods evaluate relative molecular weight distributions for polymers that produce measurable detector responses.
Mobile Phase Options
- We commonly use organic solvent systems, including THF, DMF, DMAc, chloroform, and other application-specific solvents, to dissolve and separate polymer samples.
- Buffered aqueous mobile phases accommodate polymers that require water-based chromatographic conditions.
- High-temperature trichlorobenzene (TCB) provides reliable analysis of olefinic polymers such as LDPE, LLDPE, HDPE, UHMWPE, polypropylene, and their copolymers.
- High-temperature chloronaphthalene serves as the preferred solvent for polyphenylene sulfide (PPS) applications.
- Hexafluoroisopropanol (HFIP) supports the separation of polyamides, polyesters, and high-glycolide PLGA materials.
