The internal hormones in human urine emit strong fluorescence and interfere with the determination of trace ofloxacin. However, the experiments indicate that synchronous-first order derivative fluorimetry can be applied to the determination of trace ofloxacin without interference. The linear range is 0.36-3.6 micrograms.mL-1, detection limit is 0.3 microgram.mL-1, RSD is less than 2.5% and the recovery is within the range of 101%-103%.
人尿中的内源性激素会发出强烈荧光，干扰痕量氧氟沙星的测定。然而，实验表明，同步一阶导数荧光法可用于痕量氧氟沙星的测定且不受干扰。线性范围为0.36 - 3.6微克·毫升⁻¹，检出限为0.3微克·毫升⁻¹，相对标准偏差小于2.5%，回收率在101% - 103%范围内。
