查询词典 simultaneous estimation

Methods:a solid-phase extraction and gas chromatography-mass spectrometry procedure for the simultaneous detection of tramadol and its main metabolite in urine has been developed.results:the linearity of the tramadol solution from 0.1 g/ml to 100 μg/ml is fine ,and correlation coefficient is 0.9957.the average recovery was 99.21%,and the relative sandard deviation was 2.83%.conclusion:it is a rapid,simple,accurate and sensitive method.it is also an effective method for rapid detection whether there is tramadol in urine of druggy.
