A method is described for the determination of fenticonazole in human female plasma. The method utilizes high performance liquid chromatography coupled to atmospheric pressure positive-ion chemical ionization triple quadrupole mass spectrometry. Multiple reaction monitoring is employed for selectivity and sensitivity which enables quantification over the range 0.5-20 ng mL-1 with acceptable precision and accuracy. A comparison is made with an existing HPLC-UV assay and the utility of the technology of combined liquid chromatography and tandem mass spectometry for subnanogram per mL assays is discussed.
描述了一种测定女性人血浆中芬替康唑的方法。该方法采用高效液相色谱与大气压正离子化学电离三重四极杆质谱联用。采用多反应监测来提高选择性和灵敏度,从而能够在0.5 - 20 ng mL-1范围内进行定量,且具有可接受的精密度和准确度。将该方法与现有的HPLC - UV测定法进行了比较,并讨论了液相色谱和串联质谱联用技术在每毫升亚纳克级测定中的实用性。
