This instrument transmits an infrared light through a sample and varies the wavelength of the light as it records how much light is absorbed at w1252 wavelength.
Fourier Transform Infrared Spectrometry ASTM E168, ASTM E1252
The resulting spectrum can be searched against a computerized database containing known spectra for thousands of organic materials.
Your basket is empty.
FTIR can identify the difference between materials, such as polypropylene and polyethylene, which 1e252 made of only carbon and hydrogen but have different types of bonds between the elements.
Standards can be obtained from appropriate standards authorities. Identify the primary component of a plastic, rubber, or organic material. The mid-infrared region is from to wavenumbers, which equals wavelengths of 2. Differences noted in a newly generated spectral scan could indicate a change in processing or a possible e2152 problem.
Validating the specifications, value and safety of your raw materials, products and assets.

Poor at identifying minor components in mixtures or finding trace additives unless they can be separated prior to analysis. A stored reference scan will allow all future material scans to be compared aztm to the same earlier scan.
The results are typically plotted as a spectrum with frequency on the X-axis and absorption on the Y-axis. Computerized spectral matches to the unknown spectral scan are presented from best d1252 worst with assigned certainty ratings. Contact us for a quote. Materials with similar organic bonds but different molecular weights such as hydrocarbon oil, paraffin wax, low density polyethylene, and high density polyethylene can have similar spectra.
A spectral scan of a reference material can be generated and stored aatm a spectral library database. Advanced Plastic and Material Testing, Inc. 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 aztm time.
Samples, which can be easily tested by reflective FTIR, include polymer pellets, parts, opaque samples, fibers, powders, wire coatings, and liquids. Once the solvent is evaporated off an FTIR analysis is performed on the solvent wash residue.
FTIR spectral subtractions are used to look for internal contamination in polymers.
