Near infrared spectrum spectrogram information, the spectrogram information of detection is compared with the spectrogram information in cloud storage, judges to detect
Edible oil whether be gutter oil or mixed gutter oil.
The principle of near infrared spectrum detection：Near infrared spectrum makes molecular vibration mainly due to the anharmonicity of molecular vibration
From caused by ground state to high energy order transition, the frequency multiplication and sum of fundamental frequencies of mainly hydric group X-H (X=C, the N, O) vibrations of record
Absorb.Difference near infrared absorption wavelength in different chemical environments of group (such as methyl, methylene, phenyl ring etc.) or same group with
Intensity has significant difference, and NIR spectra has abundant structure and composition information, is highly suitable for the group of carbon-hydrogen organic
Measured into property.But in NIR region, absorption intensity is weak, and sensitivity is relatively low, absorption band is wider and overlapping serious.Therefore,
It is very difficult by traditional working curve method progress quantitative analysis of establishing, Chemical Measurement develops into this problem
Solution established Fundamentals of Mathematics.Its operation principle is, if the composition of sample is identical, its spectrum is also identical, and vice versa.
As long as measuring the spectrum of sample, by spectrum and above-mentioned corresponding relation, required mass parameter data can be just obtained quickly.Root
Mixed according near infrared spectrum in the spectrogram combination cloud storage platform of near infrared spectrum detection testing sample on edible oil, edible oil
