- Description
- Specifications for NIR Spectrophotometer 1) Fourier Transform NIR Spectrophotometer in multipurpose arrangement, i.e. no need to replace the module upon changing mode of measurement. This ensures perfect alignment and speedy analysis. 2) The instrument should incorporate gold coated optics for maximum light throughput. 3) The interferometer used should be permanently aligned and its mechanism must be wear-free (frictionless) designed. 4) The interferometer must utilize retro-reflecting cube corners for instantaneous correction of instability due to mirror tilt. 5) The beam splitter used should be Quartz (or other materials with equal property) to allow maximum performance. 6) The wavenumber accuracy should be better than 0.1 cm1 and the photometric accuracy better than 0.1 % transmission to lay the foundations for a successful calibration transfer. 7) The system must allow measurement in these 3 following modest (7.1) Transmission for liquid in the wavenumber region of 4000 - 12500 cm*1 (800-2500nm) using a thermoelectrically cooled InGaAs detector. The transmission slot should be heatable up to 120C. For future measurements of various products, optional reduction inserts for various round shaped disposable vials (up to 22 mm diameter) and rectangular cuvettes should be available. (7.2) Reflection for solid sample in the wavelength region of 3600 - 12500 cm-1 (800 - 2780 nm) using PbS detector. The measurement channel should be equipped with an integrating sphere to allow capturing of light scattered from various locations of the sample. The measurement should be possible in both static sample holder and spinning sample holder for inhomogeneous samples. (7.3) Transmission for solid and semisolid sample in the wavelength region of 14250 - 9000 cm"1 (700-1100 nm) using silicon detector. The measurement channel should allow measurement of intact sample up to the thickness of at least 20 mm. 8) The system should be controlled by software. The software should be able to evaluate the condition of the spectrophotometer, acquire spectra and develop calibration equations using Partial Least Squares (PLS) regression.
