Overview
About the FI-RXF200
A research FTIR spectrometer built for the varied needs of scientific users. Resolution is better than 0.25 cm⁻¹ and the spectral range extends to 12800–350 cm⁻¹; sources and detectors can be switched automatically, and both internal and external accessories are supported.
Features
Spectral resolution
- Better than 0.25 cm⁻¹ over the full spectrum, with very high signal-to-noise ratio
- Upgradeable to higher resolution; covers the great majority of research needs
Extended spectral range
- Automatic switching of optical components extends the standard mid-infrared range (8000–350 cm⁻¹) into the near-infrared (12800–4000 cm⁻¹), for mid- and near-IR work on one instrument
- In FT-NIR, samples usually need no dilution, and because glass is transparent in the near-infrared, samples are measured directly in glass vials
Detectors
- Room-temperature DLaTGS as standard
- High-sensitivity options: liquid-nitrogen-cooled MCT, TE-cooled MCT, liquid-nitrogen-cooled InSb and TE-cooled InGaAs, for high sensitivity and throughput
- Every detector uses the latest dual-channel analogue-to-digital converter with 32-bit dynamic range, for lower electronic noise
Software
- Designed for research laboratories and simple to operate
- All operation and evaluation functions can be applied to batches of files
- Integrated fully automatic acquisition and online real-time reaction-monitoring software, for studying intermediate steps in chemical and pharmaceutical synthesis, catalytic and electrochemical reactions
