EMF-70V Vacuum Fourier Transform Infrared Spectrometer
Product Introduction
The EMF-70V Vacuum Fourier Transform Infrared Spectrometer is a high-resolution vacuum FTIR spectrometer designed for demanding infrared spectroscopy applications. Its optical and sample compartments are sealed within a vacuum system, achieving a vacuum level better than 0.2 mbar and an overall vacuum level better than 3 mbar during testing.
The vacuum optical path helps reduce interference from atmospheric moisture and carbon dioxide, improving spectral stability and measurement reliability. With a resolution better than 0.16 cm⁻¹, up to six built-in detectors, and extensive sampling accessories, the EMF-70V is suitable for advanced chemical analysis, materials research, and specialized infrared spectroscopy.

Performance Features
•  Vacuum-sealed optical and sample compartments for improved spectral stability.
•  High resolution: Better than 0.16 cm⁻¹.
•  Excellent wavenumber accuracy: ≤0.005 cm⁻¹ at 1554 cm⁻¹.
•  High signal-to-noise ratio: Better than 60,000:1 under specified conditions.
•  Up to six built-in detectors, including DLaTGS, InGaAs, Si, GaP, and MCT options.
•  Wear-free, high-stability interferometer with a collimated optical design.
• Pre-collimated, high-energy mid/far-infrared source with hot-swappable replacement.
•  Automatic accessory recognition for convenient sampling configuration.
•  Ethernet networking for remote control, data acquisition, processing, and real-time data sharing.
•  Integrated IVU verification system with self-check routines and GLP-compliant reports.
•  Comprehensive FTIR software for spectral processing, quantitative analysis, peak fitting, atmospheric compensation, and macro programming.

Working Principle
The EMF-70V operates using Fourier transform infrared spectroscopy. A high-energy infrared source emits radiation through the interferometer, which modulates the infrared beam to produce an interferogram. The beam then passes through the sample, where specific molecular vibrations absorb infrared energy.
The detector records the resulting interferogram, and the software applies a Fourier transform to convert it into an infrared spectrum. The spectrum provides information about molecular structure, chemical composition, and material properties.
The vacuum-sealed optical path minimizes atmospheric absorption from water vapor and CO₂, while the high-resolution optical system and interchangeable detectors support precise spectral measurements across a broad infrared range.
