| titleOfInvention | Method for relative quantitatification of polymers using maldi mass spectrometry |
| abstract | The present invention comprises the steps of: (S1) electrospraying a solution containing a polymer sample, a single molecule internal standard material, and a matrix through a mask to prepare a plurality of polymer samples having a thickness deviation of 30% or less for each concentration of the polymer sample; (S2) irradiating a laser to each of the plurality of polymer specimens to obtain a MALDI mass spectrum, and calculating a signal intensity ratio of the polymer sample and the single molecule internal standard material from the peak result of the spectrum; And (S3) it provides a relative quantitative analysis method of a polymer using MALDI mass spectrometry comprising the step of creating a quantitative calibration line by showing the calculated signal intensity ratio by concentration of the polymer sample. According to the present invention, a homogeneous polymer specimen having a small thickness deviation is prepared by an electrospray method using a mask to perform MALDI mass spectrometry, and at this time, the MALDI mass spectrum with reduced peak overlap due to the use of a monomolecular compound as an internal standard material. Can be obtained, from which more accurate relative quantitative analysis of the polymer can be performed. |
