紫外分光光度法是一种常用的仪器分析方法,在药物分析中应用很广泛。其灵敏度及专属性在血药浓度监测中虽然并不能令人满意,但由于紫外分光光度计较为普及,测定方法也较简单、快速,当血药浓度在μg～mg/ml 时,仍是一个值得采用的方法,此法如与适当的分离技术如溶剂提取法、层析分离法等相结合,其专属性也可以得到改善。 UV spectrophotometry is a commonly used instrumental analysis method, widely used in drug analysis. Its sensitivity and specificity in the plasma concentration monitoring, though not satisfactory, but due to the popularity of UV spectrophotometer, the determination method is relatively simple and fast, when the plasma concentration in the mg ~ mg / ml, is still a Worth to adopt the method, this method, such as with the appropriate separation techniques such as solvent extraction, chromatography, etc. combined, its specificity can also be improved.
