Fourier transform infrared spectroscopy (FTIR) is an optical analytical technique frequently used to identify organic and polymeric compounds in solid, liquid and gaseous samples. It is widely used for gaining structural information of unknown compounds in samples, residue and contaminants analysis, product development, failure analysis, investigative studies, etc.
FTIR uses infrared light to irradiate a sample and polymeric and organic compounds, present in the sample, produce their distinctive fingerprint in the form of an infrared absorption spectrum (interferograms). The FTIR software applies fourier transformations to convert this interferogram to IR spectra that are unique to the various functional groups and chemical bonds present in the sample. Comparing these spectrographs against available databases can give quantitative analysis of the compounds present in the materials.
There are different sampling techniques such as transmission, specular reflectance, diffuse reflectance, and Attenuated Total Reflection (ATR). Specular reflectance is used for both organic and inorganic samples having large, flat, and reflective surfaces. In diffuse reflectance, powder samples are examined in the form of a KBr pellet. In ATR, insoluble, multi-layer, or solid samples are analyzed using hard crystal material.

ATR-FTIR analysis of materials starts at $175/sample
Fourier transform infrared spectroscopy (FTIR) provides chemical composition and physical state information of films, solids, powders, or liquids. It is used to identify and characterize unknown materials, Identify contamination, Identify additives in polymers, etc.
Typical fourier transform infrared spectroscopy (FTIR) analysis includes quantitative analysis of organic and inorganic samples. Reference libraries are available with 1000’s standards that are used to identify materials and for quantitative analysis. Gaseous phase analysis is available where FTIR can be coupled with thermal analysis, chromatography, and rheometry.
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 is a standard test method for the analysis of sulfochromate etches solution used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
