ASTM E1252 – FTIR ANALYSIS TESTING SERVICES
Unknown spectral scans can be analyzed to determine the base material of the unknown by comparing their scan to spectral scans of known materials that are stored in a computer-based library. Your basket is empty. Click to learn more. Search all products by. Materials with large quantities of carbon carbon black or carbon fiber are difficult to obtain a usable spectral scan from because carbon strongly absorbs infrared light in a broad range of frequencies.
A typical infrared scan is generated in the mid-infrared region of the light spectrum. The objective is to look for material differences. Once the solvent is evaporated off an FTIR analysis is performed on the solvent wash residue.

However, an FTIR spectral scan alone should not be expected to identify the type of Nylon or Polyester, identify a Polypropylene or Acetal as a homopolymer or copolymer, or determine whether the Polyethylene atm a high density or low density material.
FTIR is also used for quality control of materials and for contamination analysis surface or internal. Find Similar Items This product falls into the following categories. The better the match, the higher the certainty for a correct identification of the unknown polymer. The results are typically plotted as a spectrum with frequency on the X-axis and absorption on the Y-axis.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Differences noted in a newly generated spectral scan could indicate a change in processing or a possible contamination problem.
The amount of contamination that can be detected depends on the spectral scans of the base polymer and the contaminant. FTIR is the first logical step in e12552 a polymer. Samples, which can be easily tested by reflective FTIR, include polymer pellets, parts, opaque samples, fibers, powders, wire coatings, and liquids.

Cannot detect the bonds present in most inorganic materials such as metals and some minerals. Computerized spectral searches can quickly compare an unknown spectrum to a very large number of spectra located in multiple databases in a very short period of time. A spectral scan of a reference material can be generated and stored in a spectral library database. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Samples the size of a single resin pellet can be scanned by reflective FTIR. Contact us for a quote. The mid-infrared region is from to wavenumbers, which equals wavelengths of 2. A solvent wash involves using a solvent that is nondestructive to the sample. The faster, easier way to work with standards. Certification Formally confirming that your products and services meet all trusted external and internal standards.
