Problems solved by technology

Although the septum at the injection port of the detection equipment is generally low-pollution, the septum is a rubber product after all, and it is a mixture of complex components, which will inevitably cause contamination of the injected sample and interfere with the test data
Since this injection structure has to pass through the barrier of the septum, it is also not compatible with the traditional pipette gun drop injection method.

Abstract

The invention provides a detection equipment feeding system sealing method as well as a feeding system, a device and detection equipment. A sealing device is arranged on the feeding device; when being used, the sealing device is connected with a feeding hole in a sealed manner. According to the sealing method, the feeding system, the feeding device and the detection equipment, the feeding hole is formed into an opened type feeding hole, namely, the sealing device is not arranged at the feeding hole but is arranged on the feeding device so as to seal the detection equipment feeding hole, then the contamination caused by the fact that a partitioning pad needs to be punctured when a conventional feeding device is used for feeding a sample is overcome, furthermore the interference of data is avoided, the substance detection limit is effectively reduced, and the user experience is improved. Besides, the sealing method of the feeding system of the detection equipment is compatible with various feeding modes, and a user does not need to purchase multiple types of detection equipment, so that the detection cost is lowered.

Description

technical field [0001] The invention relates to the technical field of sample introduction of testing equipment, namely a sealing method for a sampling system of testing equipment, a sampling system, a sampling device and testing equipment. Background technique [0002] Substance detection equipment includes liquid phase, gas phase, mass spectrometry, and ion mobility spectrometers. The detection limit and user experience of these substance detection equipment largely depend on the sampling method. The sampling method depends on the structure of the sampling system. A reasonable sampling system structure is the key to ensure the reproducibility of test results, avoid cross-contamination, reduce the detection limit and improve user experience. For example, in solid phase microextraction technology The pretreatment process will use the sampling system. [0003] The current substance detection equipment uses a sampling device to pierce the septum at the sampling port of the de...
