BRT-890 FTIR Spectrometer

The BRT-890 FTIR Spectrometer is an advanced, high-precision Fourier transform infrared analytical instrument featuring integrated Digital Signal Processing (DSP), an auto-aligning non-orthogonal Michelson interferometer, and a dynamic internal humidity alarm system. Engineered for high-end research laboratories, pharmaceutical QA/QC facilities, petrochemical processing, and advanced material characterization, it delivers certified molecular spectroscopy across the 7800 cm⁻¹ to 350 cm⁻¹ wavenumber range with an optical resolution better than 0.85 cm⁻¹.

Featuring an extraordinary signal-to-noise ratio (SNR > 45,000:1) and a transmission accuracy better than 0.05%, this research-grade FTIR Spectrometer utilizes an imported US-made KBr/Ge beamsplitter, a long-life air-cooled IR source, and a high-sensitivity moisture-protected DLATGS detector. Built on an integrated cast-aluminum optical bench with tool-free modular accessory positioning, the 19 kg BRT-890 combines industrial-grade structural rigidity with intelligent automated spectral acquisition.

FTIR Spectrometer FAQ

Q1: What advantage does the 45,000:1 Signal-to-Noise Ratio (SNR) provide during testing?

A: A higher SNR of 45,000:1 produces extremely smooth spectral baselines with minimal background noise. This allows for clear detection of weak absorption bands, trace component concentrations, and subtle material impurities that lower-SNR instruments might miss.

Q2: How does the Digital Signal Processing (DSP) system improve interferometer performance?

A: The integrated DSP system continuously monitors and controls mirror movement within the non-orthogonal Michelson interferometer, maintaining precise optical alignment and rapid data processing for ultra-repeatable measurements.

Q3: How does the internal humidity alarm prevent instrument damage?

A: Internal KBr beamsplitters absorb moisture over time. The BRT-890’s humidity alarm system continuously tracks relative humidity inside the optical housing and alerts the operator when the desiccant needs changing, extending optic lifespan.
