A product quality inspection fingerprint analysis device

Abstract

The embodiment of the present invention discloses a product quality inspection fingerprint analysis device, including a high-performance liquid chromatograph, a control system, and an automatic sample loading device arranged on one side of the high-performance liquid chromatograph, and the automatic sample loading device is used for In order to automatically provide a variety of samples for the high performance liquid chromatograph according to actual detection needs, the automatic sample loading device includes a sample supply part and a sampling part, and the high performance liquid chromatograph is arranged on the side of the sample supply part , a wall surface processing device is provided on the sample supply side of the sample supply part, the sampling part is provided on a side of the wall surface processing device away from the sample supply part, and the sampling part is connected to the control system, The device provided by the present invention adopts a mechanized sampling method. Before each sampling, the sampling part is cleaned by a wall surface treatment device to reduce residues attached to the sampling part, reduce cross-contamination between sampling bottles, and improve the accuracy of identification results. accuracy.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of fingerprints, and in particular to a product quality inspection fingerprint analysis device. Background technique [0002] Fingerprint refers to certain complex substances, such as traditional Chinese medicine, the DNA of a certain organism or a certain tissue or cell, and after the protein is properly processed, the chromatogram or spectrum that can mark its chemical characteristics is obtained by using certain analysis methods. , fingerprints are mainly divided into traditional Chinese medicine fingerprints, DNA fingerprints and peptide fingerprints. [0003] The fingerprint of traditional Chinese medicine refers to the chromatogram or spectrum that can mark the chemical characteristics of certain Chinese medicinal materials or preparations after proper treatment and certain analytical methods. Traditional Chinese medicine fingerprint is a comprehensive and quantifiable means of i...
