摘要
Matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF-MS) was used to analyze macromolecular compounds. The present study focused on how to use MALDI for determination of small molecules such as clenbuterol, and how to explore the matrix to improve the sensitivity. The macromolecular 1,2, 3,4-tetrakis(3',4'-hydroxyphenyl) thiophene matrix not only absorbed the laser energy but also caused sample desorption ionization. At the same time, it did not produce interfering ions of low molecular weight. Moreover, when perfluoro C-60 was added to the matrix, sensitivity was improved.
