Light-weight substance mass determination method based on near-infrared spectrometer

Abstract

The invention discloses a light-weight substance mass determination method based on a near-infrared spectrometer. The method comprises the following steps: A, respectively defining two light-weight substance samples as a control group and a prediction group; B, measuring the mass of the control group sample by using a weighing device; C, collecting spectral data of samples of the control group andthe prediction group by using a near-infrared spectrometer; D, comparing the obtained spectrum data of the control group and the prediction group, and calculating a spectrum mapping relationship therebetween; and E, calculating the mass of samples of the prediction group by combining the mass of the samples of the control group and the spectral mapping relationship. The determination method can effectively solve the problem that the same kind of light substances with different masses need to be weighed by a micrometer balance, so the measurement efficiency can be improved to a great extent, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of near-infrared detection, in particular to a method for measuring the quality of light substances based on a near-infrared spectrometer. Background technique [0002] With the progress of society, the accuracy of mass determination of certain lightweight substances is becoming more and more accurate. Traditional weighing instruments are also developing in the direction of balances in thousandths and balances in ten thousandths. Although the measurement accuracy has been effectively guaranteed, there are also problems such as high cost of measuring instruments, cumbersome operation, long measurement time, and low measurement efficiency. Especially for a certain light-weight substance, each weighing process will take a lot of time. There is no easy way to quickly weigh a single type of light-weight substance. If the mass measurement technology and near-infrared spectroscopy detection technology can be combi...
