| titleOfInvention | A method for the relative quantification of polymers using MALDI mass spectrometry |
| abstract | The present invention provides a method for relative quantitative analysis of polymers using MALDI mass spectrometry, the method comprising the steps of: (S1) electrospraying a solution comprising a polymer sample and a matrix through a mask to prepare a thickness variation according to the concentration of the polymer sample be 30% or less of a plurality of polymer samples; (S2) irradiate each of the plurality of polymer samples with a laser to obtain a MALDI mass spectrum; and (S3) use the polymer from the peak results of the MALDI mass spectrum A quantitative calibration curve was established based on the signal of the sample. According to the present invention, polymer samples of uniform thickness prepared from polymer samples of different concentrations are prepared, and reproducible MALDI mass spectra are obtained from the polymer samples, and then the polymerization shown in the spectra is used A quantitative calibration curve is established between the peaks of the chemical sample and the peaks of the matrix or internal standard, allowing the relative quantitative analysis of the polymer. |
