| 英文摘要 | Salt effect in high-voltage assisted laser desorption ionization mass spectrometry (HALDI-MS) has been studied under both positive and negative ion modes using L-tyrosine, beta-cyclodextrin, alpha-lipoic acid, as well as the complex formed between alpha-lipoic acid and beta-cyclodextrin as the test analytes. Compared the mass spectra obtained with and without the addition of salt, it is found that HALDI-MS can tolerate a higher amount of salt than electro spray ionization mass spectrometry (ESI-MS). Also, the addition of salt can enhance the HALDI-MS signal intensity of the complex ion of alpha-lipoic acid and beta-cyclodextrin, and we suggest that such signal-enhancement effect is due to the formation of the three component complex consisting of alpha-lipoic acid, beta-cyclodextrin and the positive ion of the salt. |
