How NIR Uses Light Response To Estimate Composition
The analyser collects a spectrum from the sample, then compares that response against a calibration model built from known reference samples. This model allows the NIR system to estimate the concentration or proportion of specific components, such as moisture, protein, fat, fibre, polymers, or other measurable properties.
The quality of NIR quantification depends on the strength of the calibration model, the consistency of the sample, and how closely new samples match the materials used to build the model. When properly calibrated and validated, NIR can provide fast, repeatable chemical composition results without destroying the sample.
