Near-Infrared Spectrum Analyzer for Fiber Composition Identification

System Overview:

RZNIR 7900 near infrared spectrum analyzer is suitable for qualitative and quantitative detection of textiles. The equipment has the characteristics of non-destructive, fast, source saving, environmental protection, qualitative and quantitative.

Non-destructive: use near infrared light to directly illuminate the sample to be tested in transmission or diffuse reflection. Near-infrared light has certain penetrating power and is not destructive to the sample.
Fast: The fastest scan of a single spectrum in milliseconds, coupled with the near-infrared spectrum analysis model, can achieve qualitative identification and simultaneous analysis of multi-component properties.
Source reduction: No consumables are needed, and "zero" cost detection is achieved. Simultaneous analysis of multi-component indicators is realized, which greatly saves the cost of detection and reduces the labor intensity of detection.
Environmental protection: directly obtain the near-infrared spectrum of the inner quality of the characterizing sample, without pre-treatment, avoid the use of toxic, harmful and highly corrosive chemical reagents, and prevent "secondary pollution".
Both qualitative and quantitative: Relying on the qualitative and quantitative near-infrared spectroscopy analysis model established by chemometrics to realize predictive analysis, it can realize the simultaneous predictive analysis of multiple properties of component indicators.
