QuasIR 4000 FT-NIR Spectrometer

Description

The QuasIR 4000 from Galaxy-Scientific is a compact Fourier-transform near-infrared (FT-NIR) spectrometer designed for both laboratory and field-based analysis of liquids and solids. Its dimensions of 44.5 x 24.1 x 14.5 cm and weight of 9.6 kg contribute to its portable form factor. The instrument operates across a spectral range of 4,000 to 12,000 cm⁻¹. A key technical feature is its PermAlign optics system, engineered to maintain optical alignment under varied environmental conditions, which supports consistent performance. The device incorporates an integrating sphere for reflectance and transflectance measurements and includes a separate compartment for transmission analysis. This design facilitates direct calibration transfer between instruments, aiming to reduce the need for model adjustments due to instrument variability.
