Abstract
The utility model relates to an on-line multi-channel near-infrared spectrograph for discriminating Chinese herb medicine categories and production localities, particularly an advanced spectrum testing technology developed in recent years. Traditional modes all need chemical testing modes to discriminate the traditional Chinese herb medicine categories and production localities. The utility model adopts a multi-channel detecting collection technology based on optical fiber transmission and uses a diffuse reflection spectrum to obtain the near-infrared spectrum of the traditional Chinese herb medicine. Combined with chemical metrology software and standard sample models of known categories and production localities, the utility model can quickly discriminate the categories and the production localities of unknown Chinese herb medicine. The performance of the near-infrared spectrograph achieves a national leading level, and the cost performance ratio is better than that of foreign like products.
Description
Technical field
The utility model is a kind of online multichannel near-infrared spectroscopy that is used to differentiate the Chinese medicine classification and the place of production, can realize quick online discriminating, and is practical and convenient.
Technical background
The traditional discriminating Chinese medicine classification and the method in the place of production all need to adopt the physics and chemistry identification method, comprise chemical titration, vapor-phase chromatography etc., modern discrimination method mainly comprises ultraviolet spectroscopy, infra-red sepectrometry and mass spectroscopy etc., wherein near infrared spectroscopy is because pre-service is simple, analyze fast, and can realize nondestructive analysis, thereby development prospect is considerable.
Adopting Near Infrared Measurement Technology is to grow up gradually in China recent years, at present external this technology comparative maturity, domestic pharmaceutical production producer generally finishes the discriminating of Chinese medicine by the external near infrared spectroscopy instrument of buying domestic agency, these instrument prices are expensive.
Summary of the invention
The purpose of this utility model is the design online multichannel near-infrared spectroscopy that a kind of structure is simple and direct, easy to use, pollution-free, cost performance is good.
A kind of online multichannel near-infrared spectroscopy that is used to differentiate the Chinese medicine classification and the place of production that the utility model proposes, by light source, optical fiber, integrating sphere, detector, microprocessor is formed, it is characterized in that near-infrared light source (1) splicing optical fibers (8), integrating sphere (3) is between light source (1) and sample cell frame (2), three holes (9) are arranged on the integrating sphere (3), be respectively entrance pupil, exit pupil, sample well, the signal that diffuses of sample is that integrating sphere (3) is collected, behind the integrating sphere (3) optical splitter (4), being detector (5) behind the optical splitter (4), is that microprocessor (6) connects with PC (7) serial line interface then.
During the utility model instrument test, near-infrared light source by optical fiber input to the frame of solid sample pond, collect by integrating sphere from diffusing of sample, pass through beam splitting system, finally incide on the detector, the signal that is collected by detector is connected with the PC serial line interface by microprocessor control, moves spectral analysis software on PC, the spectral information that collects is carried out analyzing and processing, adopt the cluster analysis of comparative maturity and the classification and the place of production that Discrimination Analysis Algorithm just can identify Chinese medicine.
The utility model can directly be connected with PC by serial line interface, provides convenience for the needed on-line testing of some manufacturers.
In the utility model, near-infrared light source (1) is a halogen tungsten lamp.
