| 1 | Reagent-free determination of amikacin content in amikacin sulfate injections by FTIR derivative spectroscopy in a continuous flow system显示文摘The quantitative estimation of amikacin(AMK) in AMK sulfate injection samples is reported using FTIR-derivative spectrometric method in a continuous flow system. Fourier transform of mid-IR spectra were recorded without any sample pretreatment. A good linear calibration(r>0.999, %RSD<2.0) in the range of 7.7–77.0 mg/mL was found. The results showed a good correlation with the manufacturer's and overall they all fell within acceptable limits of most pharmacopoeial monographs on AMK sulfate. | José F.Ovalles Máximo Gallignani María R.Brunetto Rebeca A.Rondón Carlos Ayala | 2014 | Journal of Pharmaceutical Analysis2014，4，2： | 1 |

| 12 | Transmission FTIR derivative spectroscopy for estimation of furosemide in raw material and tablet dosage form显示文摘A Fourier transform infrared derivative spectroscopy(FTIR-DS)method has been developed for determining furosemide(FUR)in pharmaceutical solid dosage form.The method involves the extraction of FUR from tablets with N,N-dimethylformamide by sonication and direct measurement in liquid phase mode using a reduced path length cell.In general,the spectra were measured in transmission mode and the equipment was configured to collect a spectrum at 4 cm^(-1) resolution and a 13 s collection time(10 scans co-added).The spectra were collected between 1400 cm^(-1) and 450 cm^(-1).Derivative spectroscopy was used for data processing and quantitative measurement using the peak area of the second order spectrum of the major spectral band found at 1165 cm^(-1)(SO_(2) stretching of FUR)with baseline correction.The method fulfilled most validation requirements in the 2 mg/mL and 20 mg/mL range,with a 0.9998 coefficient of determination obtained by simple calibration model,and a general coefficient of variation <2%.The mean recovery for the proposed assay method resulted within the(100±3)%over the 80%–120% range of the target concentration.The results agree with a pharmacopoeial method and,therefore,could be considered interchangeable. | Máximo Gallignani Rebeca A.Rondón JoséF.Ovalles María R.Brunetto | 2014 | Acta Pharmaceutica Sinica B2014，4，5： | 0 |
