Quantitation of synthetic polymers using an internal standard by matrix-assisted laser desorption/ionization
Abstract:
MALDI-TOF MS is utilized to perform quantitative analysis on synthetic polymers. Despite the inherent limitations of MALDI, good quantitative results have been obtained in the three sets of experiments described here. An internal standard with similar molecular properties as the analytes is introduced. Plots of relative integrated intensity ratios as a function of theoretical ratios of stoichiometry are drawn based on the results. The satisfactory slopes and correlation coefficients illustrated the practicality of quantitative measurement by MALDI-TOF MS.
