Fourier Transform Infrared (FTIR) Spectroscopy is an analytical technique used to obtain an infrared spectrum of solids, liquids or gases. Simultaneously collecting spectral data in a wide spectral range, FTIR is used to rapidly evaluate and identify materials, contaminants, adhesive performance, as well as conduct quality screenings.
The grandchild of dispersive spectrometers, FTIR systems offer advanced speed and sensitivity over their predecessors that measure from a more narrow spectra range. This capability allows rapid analysis of micro-samples down to the nanogram level in some cases, making the FTIR unmatched as a problem-solving tool in organic analysis.
The Gateway Analytical lab is equipped with a TENSOR Series FTIR Spectrometer paired with a HYPERION Series FTIR Microscope. Validated and trusted, this system affords high sensitivity performance with the permanently aligned, high throughput RockSolidTM cube corner interferometer. Powered by Bruker Artificial Intelligence Network, the TENSOR utilizes the Online PerformanceGuardTM to ensure all optical components, automation units and accessories are continuously monitored.
In addition, a dedicated ATR objective (20x) allows clear sample viewing without sacrificing infrared light throughput. After the sample positions are defined in the visual image, the ATR crystal is moved on the column mechanism to activate the infrared acquisition.
In summary, FTIR is a vital tool in identifying and comparing unknown particulate and materials in addition to many quality control investigations related to coatings, polymer heterogeneity, defects and compositional differences.
