Technical Field

Background
With the progress of science and technology and society, spectroscopy and chromatography are applied more and more widely in the field of environmental detection. The pipeline with large inner diameter can cause the increase of the dead volume of the system, the reduction of the theoretical plate number and the peak tailing, and the selection of the pipeline with too small inner diameter can increase the system pressure, increase the load of a pump and reduce the service life of a chromatographic column. The pipeline is coupled with the atomizing device to atomize the sample while being used for fluid transmission in spectroscopy.
In order to obtain an ideal analysis result, a narrow-diameter pipeline connection technology is usually adopted in chromatography and spectroscopy, the currently commonly used connecting pipeline is made of stainless steel, peek, PTFE and the like, and the narrow-diameter pipeline connection technology has a special important position in the field of environmental analysis.
Due to the small diameter of conventional tubing lines, clogging is prone to occur in the tubing lines in situations where sample filtration is inadequate or where fluid administration systems are poorly cleaned and maintained. The blockage of the lines can cause the transport of the sample to be blocked or stopped, resulting in distortion of the analysis results or a breakdown of the analysis system. Most of the current methods for replacing the blocked pipeline include three methods, the first method is to replace the blocked pipeline by adopting a replacement method, and the equipment with a narrow diameter such as an ICP or ICP-MS atomizer is usually replaced in a whole piece after being blocked, so that the use cost of the instrument is increased; the second is to adopt the ultrasonic or back pressure flushing technology, but is often limited by factors such as long pipeline length, material and blockage sites, and the like, so that the dirt which causes blockage in the pipeline is difficult to be completely discharged, and the problem of incomplete cleaning exists; the third is to adopt metal wire for dredging, because the contradiction often exists between diameter and hardness of the metal wire, the hardness of the metal wire with small diameter is not enough, the dredging effect is limited, and the hardness with large diameter is also larger, on one hand, the metal wire is difficult to be deeply inserted into the narrow-diameter transfusion pipeline, on the other hand, the distance of the metal wire to be deeply inserted into the pipeline is also limited because of the restriction of the hardness.
