摘要: Highly water-soluble hydroxylated fullerene derivatives are being investigated for a wide range of commercial products as well potential cytotoxicity. However, no analytical methods currently available their quantification at sub-ppm concentrations in environmental matrixes. Here, we report on the development and comparison liquid chromatography-ultraviolet/visible spectroscopy (LC-UV/vis) chromatography-mass spectrometry (LC-MS) based detection fullerols. We achieved good separation efficiency using an amide-type hydrophilic interaction chromatography (HILIC) column (plate number >2000) under isocratic conditions with 90% acetonitrile mobile phase. The method limits (MDLs) ranged from 42.8 ng/mL (UV detection) to 0.19 pg/mL (using MS multiple reaction monitoring, MRM). Other measurement modes MDLs 125 (single quad scan, Q1) 1.5 (multiple ion MI). Each me...
