Abstract

The invention discloses a separated multi-channel chromatographic device. The separated multi-channel chromatographic device comprises a quantitative siphon device, a detecting mechanism, a second tubular body and a reaction cavity, wherein the quantitative siphon device is used for sucking sample liquid; the detecting mechanism is arranged at the outer side of the quantitative siphon device in asleeving way, and comprises a first tubular body of which two ends are opened, and multiple test strips which are in array arrangement are arranged on the outer side wall of the first tubular body; the detecting mechanism is slidably inserted in the second tubular body; multiple connecting through holes corresponding to quantitative tube and the test strips are formed in the lower end of the second tubular body; the reaction cavity comprises at least two mutually independent reaction tanks; the upper end of the reaction cavity is rotationally connected with the lower end of the second tubularbody. Detection of multiple target detection objects can be realized through one sampling, the problems in joint detection that the sample liquid is unequally distributed, and the distribution is difficult to control are solved, multi-item detection can be simultaneously and stably carried out, high-flux detection is realized, the workload of detectors is effectively reduced, and the detecting efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of biological detection, in particular to a separation multi-channel chromatographic device. Background technique [0002] Chromatographic detection is an important form of on-site rapid detection in recent years, and it is popular in clinical, food safety, environmental testing and other fields because of its convenience and speed. At present, chromatography often requires the application of multiple test strips to detect multiple indicators on a single sample. When testing, the common practice is to place the sample liquid in a common cavity, then put the test strips in, and read the results at a specific time. This approach is only suitable for one-step chromatography and cannot be compatible with two-step methods. Moreover, the detection process with high environmental requirements in the public cavity will produce pollution, which cannot meet the detection items such as nucleic acid. Another method i...
