FTIRWe offer the the identification of organic (carbon based) materials and the characterization of organic contaminants by Fourier Transform Infrared Spectroscopy (FTIR) and Micro FTIR. Our experts use proven extraction techniques per ASTM standards to provide the best sample for analysis.
Infrared spectroscopy uses the fact that molecules have specific frequencies at which they rotate or vibrate corresponding to energy levels. FTIR uses an infrared radiation (IR) beam to modulate the wavelength of light of an IR beam directed through the sample. The beam can also be reflected off opaque samples in a process known as attenuated total reflection (ATR). Specific functional groups are represented by the absorbance of certain wavelengths of the IR beam on a spectral graph. By comparing the resulting spectrum to a database of over 20,000 organic compounds, our staff can quickly identify the matching chemical compund. Our researchers have successfully developed new FTIR/ATR methods to provide phthalate screening in children’s toys. Our primary FTIR testing instrumentation includes the following:
