Problems solved by technology

The purpose of quantitative non-destructive testing is to know the content of various elements in this sample, but the portable near-infrared detection equipment for drug sample detection in the prior art still has the following problems: 1. Drug samples have special characteristics, such as flakes and capsules etc. Due to the small contact surface of the optical fiber probe during spectrum collection, representative sample information was not collected; 2. For qualitative analysis and detection, the current domestic and foreign equipment of the same type has low precision, resulting in a large error between the detection results and the actual results. 3. The detection results of portable near-infrared detection equipment in the prior art are still unstable, resulting in unusable results; 4. Since the near-infrared detection equipment must be calibrated before use, the principle of calibration is based on the different properties and accuracy of the equipment. The natural light intensity is collected, and the calibration module is used to collect the maximum absorption rate to determine the integration time. However, due to the natural light factor of the existing portable near-infrared detection equipment, there are many uncertain factors in the calibration, and the detection results cannot be obtained accurately.

Description

technical field [0001] The invention relates to the technical field of infrared spectrum detection, in particular to a portable near-infrared spectrum detection system. Background technique [0002] Near Infrared Spectroscopy Analysis Technology (Near Infrared, NIR) is an electromagnetic radiation wave between visible light (Vis) and mid-infrared (MIR). The first non-visible light region discovered by humans in the absorption spectrum. The near-infrared spectrum region is consistent with the combined frequency of the vibration of hydrogen-containing groups (OH, NH, CH) in organic molecules and the absorption region of all levels of frequency multiplication. By scanning the near-infrared spectrum of the sample, the hydrogen-containing groups of organic molecules in the sample can be obtained. The characteristic information of the cluster, and the use of near-infrared spectroscopy to analyze samples has the advantages of convenience, rapidity, efficiency, accuracy and low cos...
