Stability and reliability
In addition to the well-known features of FT-NIR of high throughput and quick response time, the NR800 employs a newly-developed Michelson interferometer with vibration-resistant mechanism that ensures even more reliable and stable operation. Unlike other FT-NIR systems, the NR800 runs without a PC as a completely stand-alone system for on-line measurement. Analyzer operations cannot be interrupted by a PC failure nor be affected by rapid changes in PC technology.
Single detector throughout the wavelength range
The measurement wavelength range of the NR800 is from 900 nm to 2500 nm, revealing new information and offering a more accurate calibration model. A single detector InGaAs is used throughout the scanning range.
The wavelength resolution of the NR800 is from 4cm -1 . A best-fit band can be used for calibration models and measurement. High resolution is especially useful for foodstuff and pharmaceutical applications.
Calibration model transfer
Laboratory models can be applied directly to systems on the process stream, model transfer between analyzers can also be done. It realizes “seamless” transition from laboratory to process.
Double beam configuration
Double beam configuration is the standard features of NR800. It compensates disturbance of measurement originating from the change of environment conditions and affect of attenuation due to installation conditions.
Up to 4 multi-stream channels with no Optical multiplexers
The NR800 provides up to 4 channels for multiple spectrometers. Channel switching is done electrically and no mechanical moving parts are used, thus ensuring maximum reliability and fast response.
In 1993, Yokogawa released the NR500 as the first process FT-NIR for process monitoring, most parts of which such as the interferometer were specially designed from scratch for process use. The NR800 inherits the same design concept as well as field experience, and various improvements and additions have been made.
