【摘要】 在常规检测中 ,一些β-阻断剂 (或其代谢物 )的 EI质谱图极其相似 ,给确证工作带来麻烦。本文采用 GC/MS的化学电离功能得到了特征性很强的质谱图 ,使确证工作简单易行 ,并满意地应用于实际尿样分析。更多还原

【Abstract】 In the routine analysis of β blockers,when some urine were found suspicious,it was very difficult to identify the drug due to the similarities among the mass spectra of the parent drugs and many metabolites.Chemical Ionization (CI) can give more abundant mass peak on the high mass zone.The technique was applied to the confirmation of β blockers and gave a diagnostic spectrum for each compound and therefore gave definite results.更多还原
