NIRMaster™ Essential – FT-NIR Spectrometer

FT-NIR top performance

Rapidly, accurately and reproducibly control the quality and nutritional facts of your feed and food samples. The NIRMaster™ offers FT-NIR top performance as the world’s only standalone spectrometer available in food-grade PMMA or stainless steel.


Obtain reads with maximal reliability thanks to a vibration proof FT polarization interferometer. Frequent internal standard checks permanently verify the performance of your NIRMaster™ to guarantee your data remains consistently reliable. Safely operate your FT-NIR spectrometer with an embedded industry standard PC. Optimize the efficiency of your process by continuously operating your unit with protection from a twin-lamp safeguard.

Best results

Improve the reproducibility of your data thanks to polarization FT-NIR technology and the precision of your results thanks to topwavelength performance by an internal laser system. Save time with the NIRMaster™ by precisely measuring multiple parameters simultaneously.

Ease of use

Save time with efficient quick-start calibrations for FT-NIR top performance. The NIRMaster™ is compatible with standard industry monitors and keyboards to simplify your data input and management. You can confidently use your FT-NIR spectrometer in tough food production environments thanks to an easy-clean hygienic design and certified dust and splash water protection (IP54).

Easy-clean design increases food safety day by day

The hygienic easy-clean design and high ingress protection (IP) support your routine work in harsh environments. The NIRMaster™ Essential is available in food-grade PMMA housing or stainless steel housing with IP54 or IP65.

The BUCHI polarization interferometer

By using crystals with a very high refractive index, BUCHI have successfully adapted the quartz polarization interferometer. This approach makes your compact FT-IR spectrometer resistant to mechanical disturbances to offer you optimal resolution. Specifically, the FT-NIR top performance of NIRMaster in rough environments is due to the difference of spatial movements and the optical path shifts for the two light beams in a birefringent crystal of variable thickness. Mechanical distortions that dirrecly affect interefence are reduced by a factor fo 10 to 20 in a crystal interferometer compared to a Michelson type interferometer.

A twin lamp module

BUCHI have set a new standard regarding continuous use of your NIR spectrometer. NIRMaster™ Essential is designed with a twin lamp module. In the event of a disfunction of the primary source, the system automatically swtiches to a second integrated lamp. This back-up lamp lowers the risk of instrument failure and gives you enough time to order a replacement lamp. You can also continue your measurements uninterrupted for a flawless workflow.
