FTIR Spectrometer Fourier Transform Infrared Spectrometer with 45000:1 Signal-to-Noise Ratio 7800-350cm-1 Spectral Range and 0.5cm-1 Resolution

The FTIR-50 Fourier Transform Infrared Spectrometer is an advanced analytical instrument developed by our company, integrating the latest mechanical, electronic, and AI technologies. Innovative engineering delivers industry-leading light source energy transmission efficiency, interferometer stability, and receiver sensitivity — making it suitable for teaching, industrial, and research applications at every level.

The instrument uses interferometer frequency modulation. Light emitted by the source is converted into interference light by a Michelson interferometer and then directed onto the sample. The receiver captures the interference light carrying sample information, and the software derives the sample spectrum through Fourier transformation.

1. The interferometer uses a DSP-controlled, electromagnetically driven non-orthogonal Michelson design with continuous dynamic adjustment, automatically optimizing system energy without manual adjustment.
2. Dynamic collimation technology: magnetic suspension interferometer with both moving and fixed mirrors as plane mirrors, providing continuous dynamic collimation at 130,000 times per second.
3. SuperTech fully digital electronic system with digital signal output. 24-bit, 500 kHz A/D conversion and a high-speed USB interface enable real-time spectral data acquisition, ensuring data authenticity and reliability.
4. High-energy infrared single-point light source with electronic voltage stabilization and a uniquely designed built-in reflector, greatly improving light source energy utilization.
5. Excellent optical system design: the optical reflector adopts an integral SPDT cutting process to ensure high reflection efficiency and optical system consistency.
6. Built-in industrial-grade temperature and humidity display with digital readout and humidity alarm. The instrument is fully sealed to keep the entire cavity dry, greatly extending component service life.
7. Solid-state temperature-controlled diode laser.
8. Reusable 304 stainless steel box desiccant, replaceable without opening the cover.
9. Core components such as the beam splitter, detector, and window are made of KBr material with a special anti-fogging coating; moisture-proof materials such as KRS-5 and ZnSe are also available.
10. Powerful expansion capability: compatible with transmission accessories, attenuated total reflection (ATR) accessories, diffuse reflection accessories, specular reflection accessories, external reflection accessories, infrared microscopes, and more.
11. Intelligent human-computer interaction design with operation guidance, an intuitive and concise interface, and easy learning curve.
12. Rich spectral library, powerful self-built library function, and high-quality spectral retrieval.
13. Real-time display of data acquisition, with continuous display of the acquisition process and spectral preview mode.
14. The operating software includes baseline correction, data conversion, multi-component quantification, curve peak fitting, H₂O/CO₂ automatic compensation, absorbance-transmittance conversion, KK conversion, peak marking, four arithmetic operations, Y-axis normalization, QC comparison, basic analysis, and more. It supports over a dozen formats including CSV, SPA, DPT, and TXT, and allows arbitrary switching between wavenumber (cm⁻¹) and wavelength (µm).

Qualitative analysis is commonly used for the overall identification of substances. For samples that can be anticipated in advance, identification can be confirmed by comparing the sample's infrared spectrum with a standard reference spectrum. For samples that cannot be anticipated, identification is performed by searching an infrared spectral library. Our company can provide approximately 220,000 Sadtler spectra.
