| titleOfInvention | Method for relative quantitative analysis of polymer using maldi mass spectrometry |
| abstract | The present invention provides a method for relative quantitative analysis of a polymer using MALDI mass spectrometry, the method comprising the steps of: (S1) electro-spraying a solution containing a polymer sample and a matrix through a mask to prepare a plurality of polymer specimens with a thickness variation of 30% or less according to the concentration of the polymer sample; (S2) irradiating the respective plurality of polymer specimens with laser to obtain MALDI mass spectra; and (S3) creating a quantitative calibration curve from peak results of the MALDI mass spectra by using a signal of the polymer sample. According to the present invention, polymer specimens with a uniform thickness, manufactured of various concentrations of polymer samples, are prepared, and reproducible MALDI mass spectra are obtained from the polymer specimens, and then a quantitative calibration curve is created using peaks of the polymer samples, shown in the spectra, and a peak of the matrix or internal standard substance, thereby enabling relative quantitative analysis of a polymer. |
