Abstract
An object of the invention is to provide a method for enabling MS(n>) analysis of a trace amount of a sample and easily and rapidly obtaining structural information by identifying a bonding position of the labeling compound in a molecule with the MS(n>) analysis. According to the present invention, by labeling a particular moiety of the molecule in a stable manner, ions are easily generated and stabilized, thereby improving sensitivity of the MS. The amount of precursor ions generated in this manner is an amount enough to carry out the MS(n>1) analysis and to generate structure-specific ions with high reproducibility. The structural information can be easily and rapidly obtained with high sensitivity.
