  • Publication number: 20230032804
    Abstract: The present disclosure relates to a method for predicting photostability of an organic material within a short time using LA-DART-MS, the method including the steps of: irradiating a specimen containing an organic material with a laser beam; obtaining a mass spectrum of components desorbed and ionized from the specimen; and calculating a degradation yield of the mathematical expression 1 according to the present disclosure from the mass spectrum. The method for predicting photostability of an organic material according to the present disclosure as described above can predict photostability within seconds to minutes, which is a remarkably short time, as compared with a conventional method for measuring photostability of an organic material.
