FTIR Spectrometer - ToronFTIR™ 7800
FTIR Spectrometer for Pharmaceutical, Polymer, Lubricant, and Petrochemical Analysis
ToronFTIR™ 7800 benchtop FTIR spectrometer delivers high-resolution molecular and material analysis for laboratories, quality-control departments, and research facilities across many industries. The instrument builds on the Michelson interferometer principle and uses computer sampling to convert an interferogram into a complete infrared spectrum. This approach gives the analyst wide spectral coverage, high light throughput, and short measurement times in a single scan. The ToronFTIR™ 7800 serves material identification, contamination analysis, and quantitative work where confirming chemical composition matters.
The system covers a spectral range of 7800 to 350 cm⁻¹, extending from the near-infrared into the far end of the mid-infrared fingerprint region. A fully enclosed optical bench protects the interferometer and detector from moisture and airborne contaminants, so results stay stable across changing lab conditions. Operators pair the ToronFTIR™ 7800 with a broad set of sampling accessories, which lets one instrument handle solids, liquids, powders, films, pastes, and gases without a separate platform for each sample type.
Beyond routine identification, the ToronFTIR™ 7800 supports condition monitoring of in-service oils, biodiesel FAME content testing, and polymer characterization. A bundled spectral analysis suite includes a compound reference library of more than 200,000 spectra, quantitative modules, and standard-curve models. This makes the spectrometer a practical fit for pharmaceutical QC, petrochemical labs, materials research, and general analytical testing.

Theory and Method
Fourier transform infrared spectroscopy identifies materials by measuring how they absorb infrared light. Every chemical bond vibrates at characteristic frequencies, so the pattern of absorbed wavelengths forms a molecular fingerprint that reveals what a sample contains. Rather than scanning one wavelength at a time, the ToronFTIR™ 7800 records all infrared wavelengths at once. This multiplex approach collects a full spectrum in a single measurement, which shortens analysis time and improves the signal available at the detector.
At the heart of the instrument sits a Michelson interferometer. A beamsplitter divides the infrared beam into two paths: one reflects off a fixed mirror, the other off a moving mirror. When the two beams recombine, the changing path difference makes each wavelength reinforce and cancel in a pattern called an interferogram. The instrument then applies a Fourier transform, a mathematical operation that converts the interferogram into a readable spectrum of absorbance against wavenumber.
The ToronFTIR™ 7800 applies this principle with integrated gold-plated corner-cube mirrors that hold alignment without adhesives, and a DSP-driven electromagnetic interferometer that keeps the moving mirror collimated during travel. A semiconductor laser tracks mirror position for accurate wavenumber calibration, while a moisture-protected KBr beamsplitter and high-intensity air-cooled source maintain throughput across the full 7800 to 350 cm⁻¹ range.
