Tulane University chemistry professor Igor Rubtsov and a team of graduate students can lay claim to inventing an important new scientific instrument — the world’s first fully automated dual-frequency, two-dimensional infrared spectrometer.

As FTIR instrumentation has become more compact and reliable, it has experienced a type of commoditization. That does not mean that innovation has ceased.

Fourier transform infrared (FTIR) spectroscopy, a subset of infrared (IR) spectroscopy, uses a mathematical algorithm, Fourier transform, to translate raw infrared data into a spectrum. FTIR is useful for the analysis of organic and inorganic compounds that exhibit changes in polarity as a result of the vibration, spinning, or perturbation of molecular bonds. FTIR methods are common in such industries as foods, materials, chemicals, pharmaceuticals, forensics, and others. Advantages of FTIR over conventional IR are higher resolution, better signal-to-noise, easier analysis of very small samples and poorly-absorbing species, and much more rapid analysis.
