Moreover, it can also be assumed that if the leaves of 0 (2 h after application) to 10 DAA are supposed to be fed to cattle, there is a possible transfer of fipronil residues from feed to milk and thereby enter into the food chain (Faouder et al., 2007). However, leaves of the...
6. 羧酸脂肪羧酸的分子离子峰很弱,m/z 60是丁酸以上α-碳原子上没有支链的脂肪羧酸最特征的离子峰,由麦氏重排裂解产生 ;低级脂肪酸还常有M-17(失去OH)、M-18(失去H2O)、M-45(失去CO2H)的离子峰。 7. 酯羧酸酯进行α-裂解所产生(M-R)或(M-OR)的离子常成为质谱图中的强峰(有时为基峰)。
The sample solutions (10 μL) were treated with 72% H2SO4 and ultrapure water in a brown bottle at 105 °C for 2.0 h. Once cooled, the acidolysis solution was neutralised to pH 7.0 using 2.0 mM NaOH, and a portion of the sample (5 mL) was added to 10 mL of ultrapure water ...
