| titleOfInvention | A Rapid Analysis Method of Tubular Paper Ionization-Mass Spectrometry |
| abstract | A tube paper ionization-mass spectrometry rapid analysis method. First, the filter paper is cut into a triangle, and then the cut triangle is rolled into a column and embedded in a pipette tip. In this process, it is necessary to ensure that the tip of the paper matrix is 0.8-1.2mm within the The outer end of the pipette tip; after the pipette tip containing the paper matrix is prepared, it is combined with the pipette for solid-phase microextraction of target compounds in complex samples. The tip equipped with the pipette is immersed in the sample solution, and the sample solution is sucked-excluded in cycles, and the target compounds in complex samples can be enriched on the surface of the paper matrix. The entire enrichment process of the compounds to be tested takes about 30s. After washing with water, sucking a certain amount of spray solvent, loading the spray voltage for direct analysis by mass spectrometry, it has the characteristics of simple operation, long duration and high analytical sensitivity. |
