Abstract

The invention discloses a new method for online detecting crude tobacco chemical components through an AOTF near-infrared spectroscopy, and mainly relates to the technical field of the analytical chemical instrument. The method comprises the following steps: step one, mounting an online window module on an outer frame of a conveyor belt; step two, enabling crude tobacco samples to fall to the window module from the conveyor belt, and sliding to a subsequent conveyor belt through a quartz window; step three, fixing the AOTF near-infrared spectroscopy behind the window module so that a lens of the AOTF near-infrared spectroscopy is aimed at a center of circle of the quartz window and the optical distance remains stationary; and step four, when online work is carried out, all crude tobacco samples pass through the window module, wherein the AOTF near-infrared spectroscope collects the data of the crude tobacco samples through the quartz window. By detecting multi-group of data, the obtained near-infrared spectrum information is more comprehensive, the effective information is more plentiful, and the spectral analysis difficulty is reduced.

Description

technical field [0001] The invention mainly relates to the technical field of analytical chemical instruments, in particular to a new method for online detection of chemical components of raw tobacco by an AOTF near-infrared spectrometer. Background technique [0002] Modern infrared spectroscopy (NIR) analysis technology is a high-tech science and technology that has developed rapidly in the field of analytical chemistry in recent years. Near-infrared light refers to electromagnetic waves with a light wave range of 780-2526mm. Generally, the near-infrared spectrum absorption of organic substances in this area is mainly hydrogen-containing Group (OH, CH, NH, SH, PH) double frequency and combined frequency absorption, almost all the main structures and compositions of organic substances can find signals in their near-infrared spectrum, and the spectrum is stable. Moreover, it is easy to operate, rapid in analysis, and reflects the state of the measured object in real time; it...
