摘要
目的:建立拉曼光谱法快速测定盐酸异丙嗪注射液的含量。方法:采用智能激光拉曼光谱仪扫描样品,激发波长780nm,激光强度100 MW,光圈25μm,光栅400 gr·mm-1,分辨率2.0cm-1,曝光时间50 s,曝光次数2次,扫描范围100~3 200cm-1。结果:盐酸异丙嗪在20~200 mg·ml-1范围内与拉曼定量峰面积呈良好的线性关系(r=0.998 2),平均加标回收率为98.13%,RSD为1.05%(n=9)。结论:本方法快速、简单、可靠,可用于盐酸异丙嗪注射液的含量测定。
OBJECTIVE To establish a rapid raman spectroscopy method for content determination of promethazine hydrochloridne injection.METHODS Smart laser raman spectrometer was used for determination.The excitation wavelength was780 nm,laser power 100 MW,aperture 25μm,grating400 gr·mm-1,resolution2.0cm-1,exposure time 50 s,exposure times2,and the scanning range 100- 3 200 cm-1.RESULTS The calibration curve was linear over the range of 20-200 mg·ml-1(r=0.998 2),and the average recovery was 98.13% with RSD of 1.05%(n=9).CONCLUSION The method is convenient and rapid.It is able to be used in the rapid determination of injection.
