Research and quality control laboratories benefit from NIRS alike. While researchers can accelerate their experimentation, QC departments benefit from the ability to analyze hundreds of samples per day – both saving substantial amounts of time and money.

There is no need for instrument calibration. The term “calibration” is used in NIR with two different meanings:

• Unlike other NIR instruments, the BUCHI instrument does not need to be calibrated since the accuracy is ensured by internal standards and permanent laser-aided alignment.
• In NIR spectroscopy a calibration model is generally required to interpret sample data. This model needs to be developed on setup of the application. BUCHI’s NIRCal software makes it straight forward to develop robust and reliable calibrations by correlating NIR data with reference analytics.

BUCHI’s FT technology combines accuracy and robustness. Fourier Transform spectrometers grant high wavenumber accuracy and best signal to noise ratio. Polarization interferometers are insensitive to mechanical disturbances and hence ideal for rough environments.

Replace completely the reference analytics is not the target. NIR spectroscopy is a powerful technique to rapidly and reliably screen samples and therewith eliminate a lot of routine analysis. A limited amount of reference analysis is still needed to develop the initial calibration models and to periodically verify their performance.
