Providing insights into chemical and molecular structures, bonding, composition and more

Comprehensive Chemical Characterization of Polymers

Understanding the chemical composition of polymers is critical for quality control, material development, failure analysis, and contamination studies. ExcelPlas provides advanced polymer chemical testing to determine molecular structure, elemental composition, and chemical interactions at a high level of precision.

Key Analytical Techniques

We utilize state-of-the-art instrumentation to provide detailed insights into polymer chemistry. Our primary techniques include:

Fourier Transform Infrared Spectroscopy (FTIR)

FTIR, including FTIR-ATR and FTIR microscopy, is a cornerstone technique for analyzing polymer chemical structures. It detects chemical bonds and functional groups, presenting them as spectral peaks at specific wavenumbers. Our extensive spectral reference library allows for rapid identification of unknown materials, while our polymer specialists can interpret complex spectra to determine probable compositions.

Nuclear Magnetic Resonance Spectroscopy (NMR)

NMR spectroscopy provides detailed molecular-level insights by utilizing magnetism and radio waves. This technique helps to:

• Determine purity and detect contaminants
• Assess molecular environments
• Identify polymer structures

Gas Chromatography-Mass Spectrometry (GC-MS)

GC-MS is highly effective for the analysis of volatile and semi-volatile compounds (VOCs) within polymers. By separating chemical components as they travel through a column and identifying them based on mass spectra, GC-MS is invaluable for:

• Analyzing absorbed compounds within polymers
• Detecting outgassing volatiles or odors
• Investigating chemical compatibility

Elemental Analysis: SEM-EDAX & ICP

For precise elemental composition studies, we employ:

• SEM-EDAX (Scanning Electron Microscopy with Energy Dispersive X-ray Analysis) for element identification, mapping, and contamination analysis
• ICP (Inductively Coupled Plasma Spectroscopy) for quantitative elemental analysis

X-Ray Diffraction (XRD)

Our XRD capabilities enable the identification of crystal structures and phases in polymers, supporting material characterization and structural integrity assessments.

Additional Chemical Testing Services

We also provide specialized polymer chemical analysis, including:

• Degree of crosslinking assessment
• Intrinsic viscosity determination
• Gel Permeation Chromatography (GPC) for molecular weight distribution
• Immersion testing for chemical resistance evaluations
