3.3
Sample set samplecolection
A representative collection of samples that substantially covers the range of relevant component content.
3.4
Calibration sample calibrationsamples
A sample used to create a calibration model.
3.5
Verify sample validationsamples
A sample set used to verify the accuracy and repeatability of NIR host measurements.
4 Principle
Near-infrared spectroscopy (NIR) qualitative analysis method of wood is to use CH in wood,
Absorption characteristics of the near-infrared light by the over-frequency vibration or rotation of the chemical bond such as OH, and the absorption spectrum in the near-infrared region by diffuse reflection.
The correlation between the spectrum of the wood sample and the properties of the sample is established by chemometrics, thereby realizing the use of wood near-infrared spectral information.
A quick qualitative analysis of the properties of the sample.
