Automatic online liquid ultraviolet detection device

Abstract

The invention discloses an automatic online liquid ultraviolet detection device, comprising a diluent buffer bucket, a diluent feed pump, a first probe, a tee joint and a second probe which are sequentially connected in series by a main pipeline, wherein the first probe is connected with a first ultraviolet light source and a first ultraviolet spectrograph by a optical fiber; the second probe is connected with a second ultraviolet light source and a second ultraviolet spectrograph by a optical fiber; the first ultraviolet spectrograph and the second ultraviolet spectrograph are separately connected with an industrial personal computer by a cable; the tee joint is connected with a sampling buffer tank by a branch pipeline; the sampling buffer tank is connected with an extract input pipeline. The automatic online liquid ultraviolet detection device can be used for efficiently, rapidly and accurately detecting sampled liquid components in a full-automatic way, thus avoiding the influence of human factors on a detection process.

Description

technical field [0001] The invention relates to the technical field of modern extraction of traditional Chinese medicine, in particular to an automatic liquid on-line ultraviolet detection device. Background technique [0002] Traditional Chinese medicine is an important part of my country's pharmaceutical industry. It has been written into the 2025 strategic plan of Made in China. The goal of improving its processing and manufacturing level has risen to a national strategic level. The modernization technology of traditional Chinese medicine is of great significance in the overall economic and social development. . The gift of traditional Chinese medicine to the people of the world - artemisinin won the 2015 Nobel Prize in Physiology and Medicine, which further shows that modern Chinese medicine is expected to become one of my country's characteristic industries with international competitiveness and independent intellectual property rights. However, at present, in my countr...

Problems solved by technology

In this process, the quality fluctuation of different batches of extraction products is the most obvious, which is caused by the following two aspects: First, the composition of Chinese medicinal materials is complex, and the various components contained in it are easily affected by natural conditions such as place of origin and climate. The growth conditions are affected by the changes; secondly, the modern processing technology of traditional Chinese medicine is low, and the production process is extensively operated, and the extraction process conditions cannot be adjusted at any time according to the batch differences of traditional Chinese medicine raw materials.
