Problems solved by technology

However, it is difficult to use human experience to capture the spectral differences caused by the different stable states of the equipment. Therefore, the judgment method of judging that the spectrometer has reached a stable state based on experience is not objective.

Embodiment Construction

[0040] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0041] In order to make the spectral data obtained by scanning the near-infrared spectroscopy equipment in this embodiment accurately reflect the true characteristic information of the sample to be tested, it is necessary to check whether the near-infrared spectroscopy equipment used is running in a stable state before performing spectral scanning on the sample to be tested. The state is judged to avoid serious deviations in the measurement results due to the unstable operation of the near-infrared spectroscopy equipment. However, considering that the existing near-infrared spectrometer stability judgment method only judges the stability of the spectrometer based on the start-up time of the spectrometer, the accuracy of the stable state of the spectrometer is low, and a stability calculation method for near-infrared spectroscopy equipment is pr...

Abstract

The invention discloses a method for discriminating the stability of a near-infrared spectroscopy device. The method comprises a construction process of a standard sample spectrum stability model anda discriminating process of the measured spectrum stability, can be objectively discriminate the stability of an unknown scanning spectrum by constructing a stability model and calculating a stabilityindex of the scanning spectrum, and further can judge, based on the stability of the scanning spectrum, whether or not a near-infrared spectroscopy device that generates the scanning spectrum is operating at a stable state at this moment to achieve the objective judgment of the stability of the near-infrared spectroscopy device. The method has a high discriminating speed, quantifies the judgmentresult, and ensures the stability and high consistency of the operation of all near-infrared spectroscopy devices under a network state.

Description

technical field [0001] The invention belongs to the technical field of spectrum acquisition equipment, and in particular relates to a method for judging whether a near-infrared spectrum equipment has reached a stable state. Background technique [0002] Near-infrared spectrum is an electromagnetic radiation wave between visible light and mid-infrared. The spectral region is defined as the region of 780nm-2526nm. Consistent with the absorption regions of frequency doubling at all levels, the characteristic information of the hydrogen-containing groups of organic molecules in the sample can be obtained by scanning the near-infrared spectrum of the sample. The use of near-infrared spectroscopy to analyze samples has the advantages of convenience, speed, efficiency, accuracy, low cost, no damage to samples, no consumption of chemical reagents, and no pollution to the environment. Therefore, this technology is favored by more and more people. [0003] An important feature of nea...
