Abstract
Description
technical field
[0001] The invention relates to molecular ion reaction technology used in the field of tandem mass spectrometry, in particular to a gas phase molecular ion reactor device based on a radio frequency quadrupole and its realization method and application. Background technique
[0002] In the field of mass spectrometry, in order to analyze the lower content components in mixed samples, it is necessary to remove the background ions of high concentration components, and ion filtration technology is needed at this time. At the same time, as the molecular weight of the sample to be analyzed increases, isomers are very common, and the structural information of the molecule is becoming more and more important, such as the amino acid sequence of proteins and polypeptides, the structure of drugs, and the metabolites of drugs in the human body. The adducting position in DNA, the adducting position of toxic pollutants in DNA fragments, DNA base seq...
