FI-RXF100
FI-RXF100 FTIR Spectrometer
A compact FTIR spectrometer with interchangeable sampling modules. A snap-lock mount keeps the optical path strictly repeatable, so switching between ATR, transmission, reflection and other modes is easy in the lab or on site. Diamond ATR, 7800–350 cm⁻¹ with KBr optics, SNR ≥ 50,000:1, 8 kg.

Overview
About the FI-RXF100
Easy to use, capable, compact and robust: the FI-RXF100 is an infrared spectrometer that anyone can use, anywhere. For accurate, repeatable measurements day after day it uses a practically maintenance-free optical system, and a proven interferometer design gives it outstanding reliability. Its fully integrated, universal sampling makes measurement straightforward, and portable accessories are available, so it suits both the laboratory and field testing.
Sampling modules are interchangeable and lock in with a snap-lock mount that keeps the optical path strictly repeatable, so ATR, transmission, reflection and other measurement modes are easy to switch between.
Features
Hardware
- Ready to measure at switch-on; compact and robust
- Highly shock-resistant cube-corner interferometer, permanently aligned, 10-year service life
- Gold-coated mirrors for higher reflectance and better resistance to oxidation
- High-sensitivity, moisture-resistant detector
- Solid-state laser, highly stable, 10-year service life
- High-energy mid-infrared source: stabilises quickly, long service life
- Pure diamond ATR crystal for hard and corrosive samples such as minerals and sulfuric, hydrochloric and nitric acid
- Quick change between ATR, transmission, reflection and other measurement modes
- Options: fold-out touch tablet on an any-angle stand, carry case, battery and more
Software and libraries
- Intelligent identification of characteristic infrared peak positions for accurate results
- Fast mixture search: mathematical algorithms strip component spectra one after another
- The software synthesises the mixture spectrum to verify the search result and reports the relative proportion of each component
- Peak-position identification and fast spectral comparison, switchable, so the two modes cross-check each other
- Libraries cover organic compounds, inorganics, minerals, drugs and active pharmaceutical ingredients, narcotics, explosives, hazardous chemicals, polymers, packaging materials, calculi, asphalt and composites
- Optimised automatic mixture-analysis algorithm identifies mixtures more effectively
- Alarm function that names the detected substance directly, for follow-up verification by law-enforcement officers
- The software prompts when a new background is due; the background validity period is user-set
- Automatic spectrum saving and time-stamping, automatic subtraction of diamond and CO₂ absorption bands, automatic reports for export or printing
- Wi-Fi and Bluetooth for data transfer and management
Applications
- Gas analysis: real-time environmental and industrial online gas monitoring, including an established online application for ethylene glycol process gas
- Police, security and drug enforcement: identification of unknown substances such as narcotics and explosives
- Lubricating oils: authenticity checks, raw-material and product quality control, in-service oil testing and telling manufacturers apart
- Gems and jade: testing for museums and cultural heritage, and for the jewellery trade
