BRT-860 FTIR Spectrometer

The BRT-860 FTIR Spectrometer is a high-performance benchtop Fourier transform infrared analytical instrument featuring an intelligent humidity alarm system and exceptional signal clarity. Engineered for pharmaceutical research, chemical testing, polymer identification, food quality control, and academic laboratory research, it delivers accurate molecular spectroscopy across the 7800 cm⁻¹ to 350 cm⁻¹ spectral range with optical resolution better than 1 cm⁻¹.

Built with a non-orthogonal Michelson interferometer with permanent alignment, an imported US-made KBr/Ge beamsplitter, a long-life US-imported air-cooled IR light source, and a moisture-protected DLATGS detector, this high-precision FTIR Spectrometer guarantees outstanding signal-to-noise performance (SNR > 30,000:1) and transmission accuracy better than 0.05%. Equipped with an integrated cast-aluminum optical bench, dynamic humidity monitoring, and tool-free accessory recognition, the 14 kg BRT-860 combines industrial durability with automated operational safety.

FTIR Spectrometer FAQ

Q1: How does the dynamic humidity alarm feature on the BRT-860 protect the optical system?

A: KBr beamsplitters and window optics are sensitive to moisture. The BRT-860 provides active humidity monitoring and alerts operators when internal desiccant requires replacement, preventing optic damage in high-humidity lab environments.

Q2: What is the benefit of the non-orthogonal Michelson interferometer design?

A: The non-orthogonal Michelson interferometer structure optimizes mechanical beam paths, offering stable alignment, resistance to ambient vibration, and consistent baseline repeatability.

Q3: Can the BRT-860 perform quantitative analysis as well as unknown material identification?

A: Yes. The included software supports both automated spectral library searches for compound identification and peak height/area quantitative calibrations for mixture profiling.
